A medieval town encompassed by a trench, which was remodelled and shaped into a show-piece castle in the second half of the 18th and in the first half of the 19th century, represents a core of the building complex. It consists of a cylindrical medieval tower, a Gothic chapel and a courtyard. In the frame of the restoration project of the Norman Prandau complex, the improvement of the foundations and the chapel vaults, as well as its interior designing have been executed. The interior design of the castle, along with the improvement of the earlier and the production of the new exterior and interior woodwork, according to the existing patterns, have followed. The interior spaces of the castle have been designed in such a way to serve the needs of the current user, the Museum of the Town of Valpovo.
