A special agency of architects was established to design the buildings. The first group of 2,734 new housing units, called the "Cité de Montmartre" was built between the Portes of Clignancourt and Montmartre between 1922 and 1928. The new buildings were constructed of concrete and brick. The earliest buildings had many decorative elements, particularly at the roofline, including concrete pergolas. The decoration became less over the years, and over time the brick gave way gradually to reinforced concrete façades. Several new churches were built in Paris between the wars, in varied styles. The Église du Saint-Esprit (1928–32), located at 186 Avenue Daumesnil in the 12th arrondissement, was designed by Paul Tournon. It has a modern exterior made of reinforced concrete covered with red brick and a modern bell tower 75 meters high, but the central feature is a huge dome, 22 meters in diameter. The design, like that of the Sacré-Cœur Basilica, was inspired by Byzantine churches. The interior was decorated with murals by several notable artists, including Maurice Denis. The Église Saint-Pierre-de-Chaillot, at 31 avenue Marceau (16th), was designed by Émile Bois (1932–38). Its tower and massive Romanesque entrance was inspired by the churches of the Périgord region. The Church of Sainte-Odile at 2 Avenue Stephane-Mallarmé (17th arrondissement), by Jacques Barges (1935–39) has a single nave, three neo-Byzantine cupolas, and the highest bell tower in Paris. The Grand Mosque of Paris was one of the more unusual buildings constructed during the period. Intended to honor the Muslim soldiers from the French colonies who died for France during the war, it was designed by the architect Maurice Tranchant de Lunel, and built and decorated with the assistance of craftsmen from North Africa. The project was funded by the National Assembly in 1920, construction began in 1922, and it was completed in 1924, and dedicated by the President of France, Gaston Doumergue, and the Sultan of Morocco, Moulay Youssef. The style was termed "Hispano-Moorish" and the design was largely influenced by the Grand Mosque of Fez, Morocco. In the years after World War II, modernism became the official style for public buildings, both because it was new and fashionable, and partly because it was usually less expensive to build.
