The church was erected between 1610-1619, and over the next 100 years a renaissance Dominican monastery was built, which is now the exhibition. In the monastery there is the Museum of the Sejny Diocese, the Ethnographic Museum and the permanent exhibition "We were here", devoted to the St. Gimnazianum. Kazimierz. There is also the "Zapiecek" Gallery, which presents the works of local artists and serves as a tourist information point.
The Museum of the Diocese of Sejny is housed in a room called the Treasury. Its most valuable exhibits include nineteenth-century liturgical books, monstrances, chalices and bishop's stamps. The Ethnographic Museum presents collections of folk handicrafts, exhibits related to the history of local scouts and vintage radio, turntables and cameras. The exhibition is run by the Sejny Society for the Protection of Monuments.
Construction of the monastery was completed in 1706. In 1802, after the third partition of Poland, the Prussian authorities confiscated all the monastic lands, and then led to the cessation of the Order. In the next two centuries the monastery was the seat of clerical and secular educational institutions. In 1989 it became a church property.
