Rähmtor

History
On the 1648 development plan of the old castle, the present-day Rähmtor (Rähm Gate) is called "little lane toward the Mottlau." According to the drawing, it was a passageway created at that time as an extension of the Rähm, breaking through the enclosure wall of the Teutonic Order's castle. On maps, the Rähmtor is usually counted as part of the Rähm without a name of its own. In 1789 it is also called "Hagedorn's Gate."
The Rähmtor thus came into being after 1648 as a narrow opening through the wall of the Teutonic Order's castle toward the Mottlau -- hence the oldest designation. On older maps it is counted as part of the Rähm without a separate name. The only exception is the 1789 designation "Hagedorn's Gate," which derives from a personal name.
