The Lübeck Castle Gate is not as well known as the Holsten Gate but no less impressive. It is the oldest of originally four gates of the Lübeck city fortification from the Middle Ages. The Holsten Gate and the Castle Gate are the only remaining gates that are also still used today as access to the Old Town. The name of the impressive gate comes from the castle complex, which is located above the Trave River and was converted into the castle monastery of the Dominican Order in 1227. As early as the 13th century, the castle gate served to monitor the land connection to the “Queen of the Hanseatic League”. It was not until a few centuries later that the cut-through between the Trave and the Wakenitz took place.
