Bishops Palace in Włocławek, Classicist palace in Włocławek, Poland.

The Bishops Palace in Włocławek is a classicist structure with a symmetrical facade, large windows, and ornamental details characteristic of this architectural style. The building displays harmonious proportions and a clear, geometric arrangement of its elements.

A defensive castle was built here around 1330–1339 for Bishop Maciej Pałuka of Gołańczy, replacing a stronghold destroyed by the Teutonic Knights in 1329. In the 1760s the castle was rebuilt as a Baroque palace, and after 1762 Bishop Antoni Kazimierz Ostrowski gave it its present form. In 1812 it served as a hospital for wounded French soldiers, and in 1818 it was handed to the Piarist school.

The palace functions as the administrative center of the Roman Catholic Diocese of Włocławek and remains a focal point for the city's religious community. Its spaces reflect the ongoing role of the Church in local spiritual and institutional life.

Access to the palace is typically arranged through the diocesan office, which provides information about architectural features. Since the building serves religious administrative functions, visiting is possible but should be confirmed in advance.

The palace stands where a medieval castle once did, and its walls are thought to incorporate relics of that earlier stronghold. The castle had a moat up to 5 metres deep and ramparts of box construction, with a radius of only about 26–30 metres. In the 18th century one of its towers held two prison cells, lower and upper.
