Stary Dzierzgoń was one of the first Teutonic fortresses in the territory of Prussia.The castle was built in 1234 on the site of a Prussian stronghold. It was devastated in 1243 and abandoned in 1247 when the Teutonic Order moved its seat to the brand new castle in nearby Dzierzgoń. The outline of the moat and the embankments are the only remains of the fortress.
