The Church of the Assumption of the Holy Virgin, commonly referred to as "The Church of Poor Clares," is a famous landmark of the city. It is a small, Gothic-Renaissance (including Neo-Renaissance additions), single-aisle church built between 1582–1602. The interior is rather austere since the church has been stripped of most of its furnishings. Not a surprising fact, considering that in the 19th century the Prussian authorities dissolved the Order of St Clare and turned the church into a warehouse, among other uses. Nonetheless, the church is worth visiting and inspecting. In particular, the original wooden polychrome ceiling dating from the 17th century draws the attention of every visitor.
