The World of Portals and Gates brings us to the former Benedictine monastery where fragments of the original architecture are preserved.

The monastery exhibition guides us through the paradise garden to the former ambit - the cloister, which is the last remnant of the Benedictine monastery founded here in the early 12th century. The tombs of the Osovský family of Doubravice, who rewrote the history of the monastery into the history of the castle in the mid-16th century, symbolically rest in the peaceful surroundings of the cloister.

The next part of the exhibition shows a set of sacral statues from the museum collections, never exhibited before.

The religious history of the region then culminates in three smaller rooms. The first part offers an insight into the history of two major convents connected with the history of Třebíč, namely, the original Benedictine monks inhabiting and cultivating the medieval countryside and the later Capuchins who were invited to the town in the late 17th century by the lords of Waldstein castle.

The second section, devoted to the architectural development of the Benedictine convent, brings not only fragments of finds of the authentic monastery architecture, but also a virtual model of the development of the entire grounds over the centuries. This model begins with the older monastery buildings which changed into the secular Renaissance and aristocratic residence and its later Baroque modifications.

The closing part of the exhibition captures some of the tragic things that happened to the church and its representatives in the 1950s. The way the communist regime dealt with the strong religiosity of the region, instilled into the minds of local people since ancient times, is demonstrated in two precedent cases from the Vysočina region, namely in Číhošť and Babice.
