The fort shaped as a five-pointed star is surrounded by a dry moat. Inside, there is a two-tier dungeon. The fort was built in the years 1743-1745 on the northern bank of Nysa Kłodzka. Its task was to protect the places from which it was possible to fire at the city. In the 70s of the 18th century, the counter-mine galleries were developed and three fleches were erected. Since 1859, the fort has been used as a prison.
In the National Geographic Traveler plebiscite, thanks to Internet users' votes, the Nysa Fortress was recognized as the New Polish Miracle 2023 in the Opole Voivodeship.
