Fort Prusy (Fort Prussia), Nysa

Fort Prusy (Fort Prussia) in Nysa (say "NIH-sah") is the star attraction of the Nysa Fortress, a Prussian citadel laid out as a perfect five-pointed star in 1743-1745 on the hills above the Nysa Kłodzka river in southwest Poland. Seen from a drone it looks like a diagram from a military textbook; on foot you get a deep dry moat, brick casemates and underground galleries. If you like fortifications, it is one of the most rewarding stops in the Opole region and an easy add-on to a day in Wrocław or Opole.

Where it is and how to get there

Nysa is a historic town in Opole Province, about 85 km south of Wrocław and roughly an hour's drive from Opole along national road 46. The nearest airport is Wrocław; Katowice is the alternative from the east. Regional trains link Nysa with Opole and Wrocław, but a car makes it easier to combine the fort with the reservoir and nearby towns. The fort sits on the north bank of the river on Obrońców Tobruku Street, with parking in front of the water tower where the entrance is. From the Market Square it is a 20-25 minute walk across the river.

A Prussian answer to the Silesian Wars

After Prussia took Silesia from the Habsburgs in 1742, Nysa (then Neisse) became a key border fortress. The citadel was built to deny an enemy the high ground from which the town could be shelled. About twenty years later engineers added counter-mine tunnels and three outworks. In 1807 the fortress held out for months against Napoleon's allies before surrendering on June 16. From 1859 the fort served as barracks, later as a prison and, from 1914, as a military depot. A monumental water tower went up in front of the gate in the early 20th century, and between the wars a memorial hall to the town's war dead and a viewing terrace were set up there.

What to see

• The star-shaped ramparts and the dry moat, now with a paved walking and cycling path.
• Two-story casemates arranged as a pentagon under earth banks.
• Five ravelins named after Prussian provinces and cities: Pommern, Halberstadt, Mark, Magdeburg and Westfalen.
• The courtyard well, quoted at 25-32 m deep.
• The military museum and tunnels, shown on guided tours.

Tickets, opening hours and tours (as of October 2026)

Walking around the moat and ramparts is free at any time. The interiors are run by a local association: according to its booking page the fort is open on Saturdays and Sundays, noon-4 pm, with weekday visits for groups by arrangement. Guided tours last about an hour (a short talk, the museum and the tunnels) and should be booked online; bring a flashlight. Ticket types include adult, reduced, senior and family, but prices are not published, so expect to pay in PLN on site or online. No separate winter 2026/27 schedule has been announced, so call ahead (+48 694 555 768). Tours are in Polish; English is not advertised.

Is it worth visiting?

Yes, especially combined with the marked Nysa Fortress Trail, which links St. Hedwig's Bastion (tourist information, Piastowska 19), the water tower, Fort Prusy, the High Ramparts, Fort II and the garrison cemetery. Allow 1-1.5 hours for the fort and 3-4 hours for the whole trail. Kids love the tunnels; strollers manage the moat path but not the interiors.

Nearby

The Jerusalem Cemetery, a few hundred meters away, holds the grave of the German Romantic poet Joseph von Eichendorff. In the town center, see the Market Square and the Basilica of St. James; Nysa was once nicknamed the "Silesian Rome." Lake Nysa, a large reservoir, lies just west of town.
