The exhibition is located in the former Jesuit oratory over the southern nave of the Church of Sacred Heart of Jesus.

Resources collected in the museum are a great historical document of the formation of religious art in the diocese of Przemyśl over the centuries. Collection of memorabilia of the Holy Father John Paul II is placed in a separate room; it includes gifts from the Holy Father. All of the collected exhibits (e.g. vestments, numerous medals, commemorative coins) document pontificate of the Polish Pope.
