The Augustinian church and the monastery of St. Martin remained the property of the monastery until the dissolution of the order in 1866. This monastery, founded in 1353 by Prince Semowit Mazowiecki and built in the Gothic style, underwent further reconstructions in the seventeenth and eighteenth centuries to finally acquire a late Baroque form. Especially interesting is the facade and the church bell tower with preserved Gothic elements in the lower part. Under it there is a passage to the arcade courtyard of the monastery.→
