Kremper Tor, Medieval city gate in Neustadt in Holstein, Germany.

Kremper Tor is a preserved medieval city gate in Neustadt in Holstein with a stepped gable facade characteristic of northern German architecture. The structure displays traditional fortification elements and now serves as a museum housing exhibits about regional history and artifacts.

Kremper Tor is the only surviving medieval town gate on the Lübeck Bay outside Lübeck itself, a remnant of Neustadt in Holstein's former fortifications. It was renovated in 1907, and the stepped gable was added during that work. Since 2007 the zeiTTor Museum inside has been run by the town; previously it belonged to the Ostholstein-Museum in Eutin.

The gate marks the boundary between the old town center and modern Neustadt, serving as a visual reminder of the city's medieval layout and defensive past. People naturally pass through this threshold when exploring the historic district.

The zeiTTor Museum inside can be accessed through the main entrance, where exhibits display regional artifacts and historical finds. The location is easily reached on foot and sits in the heart of the old town, allowing visitors to explore nearby historic buildings and streets as well.

The gate is the only surviving medieval town gate on the Lübeck Bay outside Lübeck itself. Inside, the zeiTTor Museum shows archaeology and geology from the Mesolithic to the 12th century; its children's programme is titled "Leben in der Vorzeit". An eastern annex, reached via the museum's main entrance, holds the Cap-Arcona-Museum, founded by the town in memory of the sinking of the prisoner fleet on 3 May 1945.
