Although it was built not by Poles but by Teutonic Knights, it is located on our present-day Polish territory. It became Polish property in 1457 when Casimir Jagiellonian bought it for 190 thousand florins from Ulric Czerwonka, who took possession of the castle as a pledge for unpaid debts of the Teutonic Order. The present value of the sum for which he bought the castle is about 660 kg of gold.
