The 54m high Kröpeliner Gate, built from the 13th-century onwards, is one of Rostock's prettiest and most well known landmarks.
It is situated at the city's former western border, at the then important trade route between Lübeck, Hamburg and Stralsund. It was to underline the importance of the Hanseatic city, through its size as well as architectural-artistic elements and also to protect the city from the enemy.
In the 18th-century, it served as an arsenal. It was heavily damaged during the 2nd world War. It has been used as historical-cultural museum since 1969.
Today, it belongs to the city of Rostock and is being managed by the Verein Geschichtswerkstatt Rostock e. V.
The museum offers to tourists and interested persons an exhibition about the history of Rostock's city fortification, guided gate tours, city tours, a small library and a reading cafe.
Furthermore, there are events about regional history and monument preservation, afternoons for senior citizens and historical school projects taking place.
