Concrete has forever changed the way we conceive of places of worship, allowing for spaces that combine monumentality, light, and a powerful material poetry. Beneath its apparent simplicity, this material has opened up a vast array of formal solutions: from minimalist light boxes to habitable sculptures that engage with the landscape.
To understand why we speak of “concrete temples ” today, it is helpful to take a brief look at the evolution of religious buildings from antiquity to modernity and the avant-garde, encompassing Romanesque, Gothic, the Baroque revolution, liturgical reforms, and the experiences of the 20th and 21st centuries. This journey will also include essential examples in Japan, France, Finland, Switzerland, Germany, Spain, Brazil, El Salvador, and the United States , as well as crucial regional contexts such as Ethiopia and Norway.
What we mean by concrete temples and why they matter
When we speak of concrete temples, we are not referring to a single style, but rather to a collection of architectural works that harnessed the structural and expressive possibilities of concrete to create spaces for gathering, prayer, and contemplation with their own unique language. From exposed surfaces with the texture of formwork to thin shells and bold arches, concrete has been a vehicle for contemporary spirituality.
The material has allowed for experimentation with central forms, elliptical floor plans, large spans without supports, and almost abstract facades that breathe light , reinterpreting the basilica tradition and the cruciform plan. Natural light, filtered through slits, skylights, or glass, has become an architectural element as essential as concrete itself.
From Antiquity to Concrete: Heritages That Last
Ancient architecture laid the symbolic and technical foundations of the temple . In Greece, the harmony and proportions of the Doric, Ionic, and Corinthian orders embodied a rational ideal; in Rome, engineering genius was expressed through arches, vaults, domes, and the early use of opus caementicium (Roman concrete), key to the Pantheon and a colossal infrastructure.
Beyond their practical function, sacred buildings were manifestations of power and identity : from the Parthenon to the Roman Forum, architecture communicated status, cosmology, and social organization. Ancient cities balanced worship, public life, and political representation in temples, baths, basilicas, and amphitheaters.
Roman innovations—concrete, vaults, domes—allowed for unprecedented light and new types of buildings . Works such as the Colosseum, the Pantheon, the Pont du Gard, and Trajan's Column demonstrated how function and aesthetics could go hand in hand with cutting-edge construction techniques.
The comparison between Greece and Rome reveals two approaches: proportion and marble versus constructive grandeur and concrete . This duality would continue to resonate, centuries later, in churches that oscillate between geometric clarity and structural audacity.
From early Christianity to Byzantium: atriums, basilicas and central plans
The first Christian centuries unfolded amidst synagogues, private homes, and discreet “domus ecclesiae” . Examples such as the house-church of Dura Europos show how domestic spaces were adapted, opening walls to create rooms and small-scale baptisteries.
Under Constantine, religious worship flourished, and the Roman basilica was adopted for its large nave and capacity for large congregations . Early examples of this style emerged in Rome, such as Santa Maria Maggiore, San Giovanni in Laterano, and the Mausoleum of Santa Costanza, which strongly introduced the centralized plan.
Elements such as the atrium, the bema, and the apse transform the spatial experience . The atrium articulates the arrival, the bema elevates the altar area, and the apse focuses the gaze; from these elements derive the Latin cross plan and the subsequent definition of the transept.
Byzantium consolidated the Greek cross plan and the large, symbolic dome of heaven . Hagia Sophia synthesized the longitudinal hall and the centralized space, inspiring both Christian churches and later Islamic architecture. Eastern Christianity introduced the iconostasis and experimented with semi-domes and processional axes.
Patronages, relics and style overlaps
The complexity of many churches is explained by patronage, location, relics, and the status of each community . Abbeys and collegiate churches, with more skilled architects, exhibit greater refinement; churches with relics or on pilgrimage routes grow in scale and ambition.
Reforms, centuries of construction, and changes in worship gave rise to unique hybrids . The Cathedral of Santiago de Compostela adds its imposing Baroque Obradoiro façade to a Romanesque structure; Santa María del Fiore blends Gothic and Renaissance styles; the Pantheon and the former baths, transformed into Santa María de los Ángeles, were repurposed for Christian worship; the Mosque of Córdoba incorporated Christian interventions after the Reconquista.
Romanesque and Gothic: from load-bearing walls to a skeleton of stone and light
Romanesque architecture, promoted by Cluny and later refined by the Cistercians, adopted the Latin cross plan with ashlar walls, semicircular arches, and barrel vaults . Lateral thrust was countered with buttresses, and the iconographic program depicted scenes from the Bible and martyrdoms; in Spain, variations in brick and adobe appeared, such as San Tirso de Sahagún.
Cistercian austerity cleanses figurative decoration and prepares, paradoxically, for the Gothic leap , where pointed arches, ribbed vaults and flying buttresses relieve the structure, opening up space for enormous openings of radiant stained glass and complex tracery.
Gothic architecture elevates engineering to a theological art: greater width means greater height . Colored light, naturalistic sculptures, and refined geometry transform cathedrals into veritable "bibles in stone." The style spreads to market halls, town halls, and guildhalls.
Renaissance, Baroque and Reformation: new perspectives on sacred space
The Renaissance revived antiquity and experimented with domes and central plans . Brunelleschi designed the dome of Florence; Bramante designed St. Peter's Basilica in Rome; in Spain, the Sacra Capilla del Salvador in Úbeda and the monastery of El Escorial, a Herrerian emblem of monumental sobriety, shone brightly.
Catholic Baroque, with the Church of the Gesù as its paradigm, reimagined the single nave and interconnected side chapels , eliminated the narthex, and concentrated the congregation around the altar. Elliptical domes, curved facades, illusionistic frescoes, and zenithal lighting sought to move the faithful. St. Peter's culminated with Bernini and his colonnade; its influence reached St. Paul's in London and great Latin American cathedrals.
The Protestant Reformation shifted the focus to the pulpit and the listening to the Word . Pews were reoriented, images were removed, and new architectural styles emerged that maximized visibility and acoustics; in the Netherlands, the octagonal church of Willemstad appeared; in Silesia, the monumental Churches of Peace, made of wood and without towers , arose under strict restrictions, followed by the Gnadenkirchen.
Neoclassicism reacted to the excesses of the Baroque with temples of sober monumentality . The Madeleine in Paris reproduces the language of the classical temple; the Parisian Pantheon and, in Italy, San Francesco di Paola or the Gran Madre di Dio adopt the model of the Roman Pantheon; the cathedrals of Pamplona and Buenos Aires also stand out.
From historicism to modern concrete: neo-Gothic, modernism and avant-garde
The 19th century saw a revival of Gothic architecture (from literal copies to free interpretations), culminating in cathedrals like Cologne and Milan and erecting iconic landmarks such as Liverpool and St. Patrick's Cathedral in New York . Even the Salt Lake City Temple incorporates a powerful vertical rhetoric.
Modernism broke with academic styles, but penetrated religious architecture with a few masterpieces . Antoni Gaudí experimented with the Crypt of the Colonia Güell and designed the Sagrada Familia with a baldachin over the altar, reinterpreting tradition and nature with modern materials.
In the interwar period, Auguste Perret at Le Raincy and, later, Le Corbusier at Ronchamp, ushered in a new sacredness of concrete . Bare spaces, deep light, and honest structure paved the way; Rudolf Schwartz and the Bauhaus influence at Corpus Christi (Aachen) proposed a minimal "theocentricity," with white walls and essential furnishings.
The Second Vatican Council promoted active participation and a freestanding altar facing the people . Experiments were conducted with circular or polygonal floor plans (Liverpool Metropolitana, Brasilia), amphitheater-style proscenium configurations, and routes through distinct areas (baptism, the Word, the Eucharist), according to contemporary liturgical proposals.
Brutalism and Spanish examples: Mediterranean light in concrete
In Spain, ecclesiastical brutalism picks up the torch of the honest and luminous concrete of the 50s and 60s . La Porciúncula, in Palma, is a work that looks to the past from a resounding material modernity, marked by a tragic episode: the murder of the architect José Ferragut in 1968, never solved and surrounded by hypotheses that point to the homophobia of the time and his critical stance against the development of the Balearic coast.
The Porziuncola church remains as a tribute to a way of capturing Mediterranean light with concrete , demonstrating how the roughness of the material can become warm when it dialogues with well-oriented clerestories and skylights.
In Jávea, Our Lady of Loreto (1968) by Fernando García Ordoñez made the city a benchmark of European brutalism . Shaped like a fishing boat, twelve curved pillars evoke the apostles; skylights comb the walls so that the light "glides" through, and, looking up, the roof resembles the belly of a ship ready to fish: a symbolic power that embodies the renewing spirit of the Second Vatican Council.
Ten essential concrete temples in the world
Church of the Light, Osaka (Tadao Ando, 1989) . Exposed concrete walls and a hollowed-out cross that lets in the eastern light: radical minimalism in the service of contemplation.
“Saint Basil’s Cathedral”, in France (Auguste Perret, 1923) . Presented as an early landmark of reinforced concrete with parabolic arches and a unique bell tower, it reflects the pioneering exploration of the material in European worship; it is mentioned in this context as an example of the structural and expressive use of concrete in the sacred architecture of its time.
Chapel of Silence, Helsinki . An urban refuge of concrete and wood, with a bare interior and a vaulted ceiling designed to provide acoustics for inner retreat in the heart of the city.
Church of San Giovanni Battista, Mogno (Mario Botta) . Local pieces of stone and concrete in an elliptical plan, a building that stands authoritatively in the alpine landscape.
Bruder Klaus Chapel, Germany (Peter Zumthor) . Cast-in-place walls, smoky and conical interior that leads the eye to a minimal sky: austerity that moves.
Saint-Pierre Church, Firminy (Le Corbusier) . Sculptural form and cylindrical tower; small openings allow beams of light to pass through, dramatizing the modernist and brutalist space.
Santa María Reina de la Paz, San Diego (Philip Johnson and Richard Foster) . Concrete structure with a shop-like profile, large glazed areas and an open and welcoming atmosphere.
Cardedeu Chapel, El Salvador (EMC Arquitectura) . Concrete columns and beams support a “floating” roof that frames the lake and merges interior and landscape.
Metropolitan Cathedral of Brasilia (Oscar Niemeyer) . Hyperboloid of 16 curved columns: light, structure and national symbol in a single monumental gesture.
Church of Saint Francis of Assisi, Pampulha (Oscar Niemeyer) . Waves of concrete that follow the terrain, a sober interior and abstract stained glass windows of memorable plasticity.
Beyond Concrete: Regional Traditions That Define the Temple
The architecture of Orthodox Tewahedo in Ethiopia combines ancestral basilicas, rock-hewn churches, and circular typologies with conical roofs . The interior is organized into three rings: the maqdas (tabot sanctuary), the qiddist (for communicants), and the qene mehlet (accessible to all), highlighting the hierarchy of the rite.
In Norway, wood has reigned supreme: from medieval stave churches to octagonal and cruciform plans designed to withstand the wind . After World War II, reinforced concrete (Bodø Cathedral) and solutions using metal panels, such as the Arctic Cathedral, emerged, demonstrating how material and climate shape form and symbolism.
Iberia between two worlds: Visigoths, Mozarabs and Mudejars
Before and after Al-Andalus, the Iberian Peninsula blended various heritages . The Visigoths adopted the horseshoe arch (San Juan de Baños, San Pedro de la Nave); Asturian art (San Julián de los Prados, San Miguel de Lillo, Valdediós) merged with Carolingian art; and the Mozarabs combined Eastern-inspired painting with small hermitages like San Baudelio de Berlanga, with its dome on a central pillar.
Mudéjar architecture, with its brick, tile, and plasterwork, filled facades and interiors with geometric patterns . Aragon preserves World Heritage treasures; and its Neo-Mudéjar reinterpretation, in the 19th century, resulted in churches such as San Fermín de los Navarros in Madrid.
Liturgical modernity, postmodernity and global diversity
The second half of the 20th century consolidated the stylistic dispersion: from rationalism to postmodern expressions that recover symbolic memory . Authors such as Steven Schloeder, Duncan Stroik, and Thomas Gordon Smith have advocated for a legible continuity of traditional Christian language from contemporary perspectives.
There are also critical voices: in Nigeria, during the 20th century, some churches went from looking like foreign monuments to adopting industrial features , reminding us that form and symbol must engage with local culture and the experience of the faithful.
Conservation, tourism and bibliography: keeping stone and concrete alive
The current challenge is to conserve without distorting . Monuments like the Parthenon or the Colosseum require minimally invasive techniques (laser restoration of marble, artisanal restoration), and tourist pressure necessitates managing visitor flows and relying on virtual reality for protection and promotion.
Classical tradition inspired the Renaissance and Neoclassicism, and its echoes continue to resonate in architectural theory . From Vitruvius to modern treatises, and authors such as D.S. Robertson, F.D.K. Ching, Carolyn Y. Yerkes, Leland M. Roth, Aldo Rossi, and Ricardo Aroca, scholarly literature has helped us understand how history, technique, and worship intertwine. Romanesque galleries and academic studies (including university documents) expand upon the context and provide further detail.
If we could only visit one building in Rome, many would choose the Pantheon for its imperishable concrete dome , because it embodies the continuity between ancient heritage and the power of the material that, centuries later, would once again star in amazing temples.
Looking back, concrete has allowed us to rediscover light, silence, and scale in the temple ; from Ando's minimalism to Zumthor's poetry, passing through Niemeyer's audacity or the resounding brutalist sincerity of the Porciúncula or Loreto in Jávea, we see that there is not a single "concrete style," but a common language to express faith with material and spatial honesty.
