The palatial Jesuit grammar school with its towers and magnificent portals on the south side of the square was built in 1694-1701 and has housed the town hall of the city of Koblenz since 1895 (Town Hall Building I). In the south-east corner of Jesuitenplatz is the former Jesuit Church (now the City Church). It was built in 1613-17. In the centre of the square, which is surrounded by beautifully restored town houses, stands the monument to the Koblenz physiologist and anatomist Johannes Müller, which dates from 1899.
