Notre Dame du Haut was designed by Franco-Swiss architect Le Corbusier, it is an example of twentieth-century religious architecture.
Notre Dame du Haut was thought of as a more extreme design of Le Corbusier's late style. Commissioned by the Association de l'Oeuvre Notre Dame du Haut, the chapel is a simple design with two entrances, a main altar, and three chapels beneath towers. Although the building is small, it is powerful and complex. The chapel is the latest of chapels at the site. The previous chapel was completely destroyed there during World War II. The previous building was a 4th century Christian chapel. But, at the time the new building was being constructed, Corbusier wasn't exactly interested in "Machine Age" architecture. He felt his style was more primitive and sculptural, so he decided to build something more interesting.
The site is high on a hill near Belfort in eastern France. There had been a pilgrimage chapel on the site dedicated to the Virgin Mary, but it was destroyed during the Second World War. After the war, it was decided to rebuild on the same site. The Chapelle Notre-Dame-du-Haut, a shrine for the Roman Catholic Church at Ronchamp, France was built for a reformist Church looking to continue its relevance. Warning against decadence, reformers within the Church looked to renew its spirit by embracing modern art and architecture as representative concepts.
The chapel at Ronchamp is singular in Corbusier's oeuvre, in that it departs from his principles of standardisation and the machine aesthetic, giving in instead to a site-specific response. By Le Corbusier's own admission, it was the site that provided an irresistible genius loci for the response, with the horizon visible on all four sides of the hill and its historical legacy for centuries as a place of worship.
This historical legacy was woven in different layers into the terrain - from the Romans and sun-worshippers before them, to a cult of the Virgin in the Middle Ages, right through to the modern church and the fight against the German occupation. Le Corbusier also sensed a sacred relationship of the hill with its surroundings - the Jura mountains in the distance and the hill itself, dominating the landscape.
The structure is made mostly of concrete and is comparatively small, enclosed by thick walls, with the upturned roof supported on columns embedded within the walls, like a sail billowing in the windy currents on the hill top. The Christian Church sees itself as the ship of God, bringing safety and salvation to followers. In the interior, the spaces left between the walls and roof and filled with clerestory windows, as well as the asymmetric light from the wall openings, serve to further reinforce the sacred nature of the space and reinforce the relationship of the building with its surroundings. The lighting in the interior is soft and indirect, from the clerestory windows and reflecting off the whitewashed walls of the chapels with projecting towers.
Some have described Ronchamp as the first Post-Modern building. It was constructed in the early 1950s.
The main part of the structure consists of two concrete membranes separated by a space of 6'11", forming a shell which constitutes the roof of the building. This roof, both insulating and watertight, is supported by short struts, which form part of a vertical surface of concrete covered with "gunite" and which, in addition, brace the walls of old Vosges stone provided by the former chapel which was destroyed by the bombings. These walls which are without buttresses follow, in plan, the curvilinear forms calculated to provide stability to this rough masonry. A space of several centimeters between the shell of the roof and the vertical envelope of the walls furnishes a significant entry for daylight. The floor of the chapel follows the natural slope of the hill down towards the altar. Certain parts, in particular those upon which the interior and exterior altars rest, are of beautiful white stone from Bourgogne, as are the altars themselves. The towers are constructed of stone masonry and are capped by cement domes. The vertical elements of the chapel are surfaced with mortar sprayed on with a cement gun and then white-washed - both on the interior and exterior. The concrete shell of the roof is left rough, just as it comes from the formwork. Watertightness is effected by a built-up roofing with an exterior cladding of aluminium. The interior walls are white; the ceiling grey; the bench of African wood created by Savina; the communion bench is of cast iron made by the foundries of the Lure.
The South wall of Ronchamp is a creature of its own. Rather than designing a straight, 50 cm thick concrete piece, Le Corbusier spent months trying to perfect the outside partition. What he came up with is a wall that starts out as a point on the east end, and expands to up to 10 feet thick its west side. As it moves from east to west, it curves towards the south. To further expand his design's complexity, Le Corbusier decided to make the windows of the wall extraordinary. The openings slant towards their centers at varying degrees, thus letting in light at different angles in the interior. Furthermore, the glass that closes them off is set at alternating depths. This glass is sometimes clear, but is often decorated with small pieces of stained glass in typical Corbusier colours: red, green, and yellow. These stained pieces radiate like rubies, emeralds, and amethysts, and act as the jewels of the already complex wall. After this extensive design, Le Corbusier decided not to make the southern partition a bearing wall. Instead, the building's roof is supported by concrete columns that make it appear to float above the rest of the space.
In a final move of symbolism, Le Corbusier filled the inside of the wall with the rubble from the previous chapel that stood at the location. Thus the old church, and all of its history, would remain in the site.
Small pieces of stained glass are set deep within the walls, which are sometimes ten feet thick. The glass glows likes deep-set rubies and emeralds and amethysts and jewels of all colors.
Because it is a pilgrimage chapel, there are few people worshipping at most times. But on special feast days, large crowds of thousands will attend. To accommodate them, Le Corbusier also built an outside altar and pulpit, so the large crowds can sit or stand on a vast field on the top of the hill. A famous statue of the Virgin Mary, rescued from the ruins of the chapel destroyed during WWII, is encased in a special glass case in the wall, and it can be turned to face inward when the congregation is inside, or to face outward toward the huge crowds.
Much like the church at the monastery at La Tourette, the roof of Notre Dame du Haut appears to float above the walls. This is possible, because it is supported by concrete columns, not the walls themselves. The effect produced allows a strip of light to enter the building, thus lighting the space further, and making the church feel more open.
This billowing concrete roof was planned to slope toward the back, where a fountain of abstract forms is placed on the ground. When it rains, the water comes pouring off the roof and down onto the raised, slanted concrete structures, creating a dramatic natural fountain.
Frank Gehry argues that the problem with the chapel at Ronchamp is that it is impossible to hold back tears while visiting it.
