St Martin Rotunda

Vratislav II's little Romanesque chapel, St. Martin Rotunda, dates from the 11th century. It is Prague's oldest surviving building. Recently, archaeologists discovered that it actually contains a secret underground floor that for centuries nobody knew existed. Located in Vysehrad, the rotunda is closed to the public.
