The lower gate, in which the city prison was temporarily housed on two levels in four dungeon cells, once resembled the upper gate, like the latter it had a multi-storey structure, but no hood with a clock, but a simple, laterally cranked roof. The drawing (left) was made in 1788 when the prison in the tower was built.
In the course of his life, the dimensions of the gate no longer corresponded to the larger carts of increasing trade. Cars often had to be unloaded, sometimes cobblestones had to be removed to allow passage.
In 1837 the magistrate therefore applied for the gate, which had meanwhile also become dilapidated, to be completely demolished.
The royal Bavarian government allowed the demolition, but decreed that a new gate system would have to be built afterwards, which should do justice to the character of a walled city.
As a result, the Lower Gate was rebuilt in its present form as a simple round arch gate with an imitation tower on both sides (1.68x1.68m) and battlements made of red sandstone. The round arch spans a width of 4.30 m.
The side pedestrian passages were added later. The passage on the right out of town at the former beneficiary garden, now a kindergarten, already existed around 1900. The other passage was not created until the late 1950s.
