Braniewo Castle

Braniewo Castle, also known as Bischofsburg Braunsberg, is a historic Gothic fortress located in the town of Braniewo within the Warmian-Masurian Voivodeship of Poland. Constructed between 1279 and 1300 during the tenure of Bishop Heinrich Fleming, the structure originally served as a residence for the Warmian Bishops. Its ruins are situated on the south-eastern side of the Old Town, adjacent to St. Catherine's Basilica. The castle played a pivotal role in the region's administration until 1340, when the episcopal residence was relocated to Orneta, after which the site became the seat of the local Burgrave.

The castle possesses a turbulent history marked by military conflict and changing ownership. In 1454, it was seized by the Kingdom of Poland, serving again as a bishop's residence until 1461. During the 17th century, the fortress faced occupation by Swedish forces under Gustavus Adolphus in 1626 and again from 1633 to 1635. The Swedes significantly altered the site by constructing bastions and bulwarks around the original structure. Over subsequent centuries, parts of the fortifications were dismantled, and by 1811, the building was repurposed to house a school, reflecting its transition from a military stronghold to a civic institution.

Today, Braniewo Castle exists only as fragmented remains following its destruction during the Vistula–Oder Offensive in 1945. The majority of the ruins were deconstructed in 1958, leaving behind a single surviving tower that features a chapel on its second floor. While the extensive fortifications and main residential wings have vanished, this remaining tower stands as a testament to the site's medieval origins and its long history of religious and military significance in northern Poland.
