The Archdiocesan Museum is devoted to the conservation of works of art of the Olomouc Archdiocese. Its collections are shown in the Chapter Deanery at the Premyslid Castle, a location representing thousand years of history, from the remnants of the Bishop's and Prince's Palaces to Baroque and Rococo.

The Olomouc Premyslid Castle and Archdiocesan Museum are a focal point of Moravian presence in European history. It is an early centre of Christianity, a place that preserves and highlights the high level of artistic patronage of the archbishops of Moravia, and a fine example of heritage conservation in the region.
