Peenemünder Schanze, Archaeological monument at northern tip of Usedom Island, Germany.

Peenemünder Schanze is a former fort at the northern tip of Usedom, where the Peene River meets the Baltic Sea. Built in 1628 as a star-shaped earthwork, it was later reinforced with casemates and brick buildings. Its outer wall and moats formed a rectangular star, with a square main redoubt in the centre surrounded by water ditches.

A customs and pilot station stood here in the 15th century, collecting the Pomeranian Prince's Toll. In 1628 Wallenstein had a star-shaped earthwork thrown up at the narrowest point of the Peene Strom; Gustav II Adolf landed and took it without resistance on 24 June 1630. It belonged to Sweden from 1631 to 1721, then to Prussia, which dismantled it in 1871.

The fortification played an important role in protecting trade routes and collecting tolls from ships entering the region. Visitors can still observe how strategically important this location was for controlling water traffic.

The fort lies at the northern tip of Usedom on the narrowest point of the Peenestrom, within the protected Peenemünde archaeological monument landscape. It is a protected ground monument since 1955, so the earthworks should be viewed from the marked paths rather than walked over. The site is reached on foot from Peenemünde village.

The fort was not dismantled in 1759: that year, during the Seven Years' War, a shell hit the main powder magazine and the explosion destroyed much of the rampart and wounded 60 men. The site remained in Prussian hands until its final demolition in 1871, and it has been a protected archaeological monument since 1955.
