Art Deco structures in Brussels include the Residence Palace (1927) (now part of the Europa building), the Centre for Fine Arts (1928), the Villa Empain (1934), the Town Hall of Forest (1938), and the Flagey Building (formerly known as the "Maison de la Radio") on Eugène Flagey Square (1938) in Ixelles. Some religious buildings from the interwar era were also constructed in that style, such as the Church of St. John the Baptist (1932) in Molenbeek and the Church of St. Augustine (1935) in Forest. Completed only in 1969, and combining Art Deco with neo-Byzantine elements, the Basilica of the Sacred Heart in Koekelberg is one of the largest Roman Catholic basilicas by area in the world, and its cupola provides a panoramic view of Brussels and its outskirts. Another example are the exhibition halls of the Centenary Palace, built for the 1935 World's Fair on the "Heysel"/"Heizel" Plateau in northern Brussels, and home to the Brussels Exhibition Centre (Brussels Expo).
