Around 1400, a new urban extension was built in the north of the city, the Ulmer Vorstadt. After the wall, the Ulmer Tor emerged as the northern sally gate. The tower was not finally expanded until 1445. In 1489, Maximilian I, as Roman-German king, entered his imperial city of Memmingen with a large entourage through the gate. During the Peasants' War, the Upper Swabian bunch came through the gate into the city with 900 men and wrote down the Twelve Articles in the Kramerzunft, the first human rights declaration in the world. When Wallenstein entered the city from Ulm in 1630, he was also escorted through the gate to the Fugger building. The Swedes, not wanting to be inferior to Wallenstein, also moved into the city through the Niedergassentor in 1634 and also resided in the Fugger building. When the Imperials again besieged and defeated the city in 1647, they entered the city through the gate. In 1702 the goal was unsuccessfully defended against Bayern, but it remained undamaged. During the last great siege and capture of the city by the French, the gate was occupied by the Austrians after their departure. In 1821 the gate was closed. Since then, the drawbridge and the wooden gates have been missing.
