Kołobrzeg Fortress

Kołobrzeg Fortress is not a single castle but a scattered set of forts, redoubts and earthworks around the harbor and town of Kołobrzeg (roughly "ko-WOB-zheg"), on Poland's Baltic coast. For more than two centuries, from 1653 to 1872, this Prussian port was one of the key strongholds on the southern Baltic, and in 1945 it became "Festung Kolberg" in one of the last big battles on the coast. Today the surviving pieces are linked by two easy walking routes – a rewarding thing to do in Kołobrzeg beyond the beach.

Where it is

Kołobrzeg (German: Kolberg) lies in West Pomerania, about 230 km northeast of Berlin; the nearest airport is Szczecin-Goleniów, about 100 km away. The fortifications cluster around the mouth of the Parsęta River, within walking distance of the spa district and the train station.

A short history

After the Thirty Years' War the town passed to Brandenburg, and from 1653 Elector Frederick William turned it into a modern bastioned fortress. It was tested repeatedly:

• In the Seven Years' War, Russian forces besieged Kolberg in 1758 and 1760 without success, and in December 1761 the garrison surrendered after a long blockade.
• In 1807 Napoleon's troops, including a Polish infantry regiment, laid siege to the town. The defense, led by August Neidhardt von Gneisenau with the burgher Joachim Nettelbeck and Ferdinand von Schill, held out until the Peace of Tilsit and became a Prussian national legend.
• In 1832–1836 the fortress was modernized; many surviving works date from this phase.

The land fortress was abolished in 1872 (the sea fortress in 1887), and Kolberg grew into a fashionable seaside spa. In late 1944 Hitler declared it a fortress again. The battle lasted from March 4 to 18, 1945; Polish and Soviet troops took the city, whose historic center was almost completely destroyed. Kołobrzeg then became part of Poland.

What to see: the Three Forts Trail

This walking and cycling route links the harbor defenses:

• Fort Ujście (1770–1774), the round brick fort that now carries the lighthouse;
• Morast Redoubt (1770–1774), a five-sided redoubt in the marina on Salt Island, restored in 2018;
• Salt Redoubt (Reduta Solna, 1832–1836) by the fishing port, next to the Maritime Open-Air Museum.

The forts sit on both sides of the river mouth; allow about an hour.

The town fortifications trail

A second route through town includes Fort Wilczy (1807), scene of the fiercest fighting in 1807 and an open-air amphitheater since 1925; the Stone Redoubt (Kamienny Szaniec, 1832–1836) on the eastern beach; remains of the Pomorze Bastion in Dąbrowski Park; the Radzikowo Gate of 1708; and the 17th-century Knights' Academy building.

Visiting tips

The outdoor remains are free and open all year. Paid sights along the way include the lighthouse on Fort Ujście (October 10 a.m.–6 p.m., November–January 10 a.m.–4 p.m.; 15 PLN, as of October 2026) and the Maritime Open-Air Museum (shorter winter hours – check before you go). Plan 3–4 hours for both trails. Many relics are grassy ramparts, so wear sturdy shoes. The Museum of Polish Arms in town adds context on the sieges of 1807 and 1945.

Getting there and nearby

Start at the lighthouse on ul. Morska, about 2 km from the train station. Parking in the center and spa district is paid and tight in summer, so walking or cycling (the R10 Baltic coast cycle route crosses town) is easiest. Nearby: the pier, the Poland's Wedding to the Sea Monument, the east breakwater and Żeromski Park.
