Former Town Hall and Market Church, Mannheim: Detail

St. Sebastian is the oldest Catholic parish church in the city of Mannheim; it served both as the market church (Marktkirche) and as a reception court church for the use of the Palatinate Electors. It was built as a double structure with the city hall; this is now the oldest surviving building in the city. The building is characterized by the distinctive interplay between light and surfaces of white plastered red sandstone.
