Ludwigstor

Here, too, a mighty structure - in the middle of a gate leads through. On the outside, both the Bavarian King Ludwig I and the builder of the fortress Colonel Friedrich Ritter are depicted in armor. In the building is the city and fortress museum.

City gate built in 1840 as part of the fortress construction.
Originally called "Deutsches Tor".
It houses the city and fortress museum,

There were originally two entrances to the city, namely the Ludwigstor (originally German Thor) in the northwest and the Weißenburger Tor (originally French Thor) in the east.

In the immediate vicinity of the Ludwigstor is the entrance to the city and fortress museum, which I can highly recommend.
Opening times (April - December):
Every 1st Sunday of the month from 10 a.m. to 5 p.m. and every Wednesday from 2 p.m. to 6 p.m.
