The Archdiocesan Museum is housed in the renovated buildings of the chapter deanery on Wenceslas Square. The tour includes the Romanesque Bishop's Palace (formerly known as the Přemyslid Palace) and the Chapel of St. Barbara.

The sightseeing of the renovated buildings is a unique experience of its own. They demonstrate the architectural and artistic progress at the site of the so-called Olomouc castle on Wenceslas hill throughout the last millennium - from the remains of the royal palace through the high Romanesque, Gothic and Renaissance periods to the late Baroque and Rococo interiors.

The permanent exhibition of the Museum introduces visitors to the spiritual culture of the Olomouc Archdiocese. A picture gallery shows marvellous paintings collected by Olomouc bishops since the 16th century. A concert hall called "Mozarteum" is part of the premises. It has been named to commemorate the stay of the famous composer at this place.
