The Ludwigstor is part of the Fronte Karl, named after the royal prince of Bavaria Karl Theodor Maximilian August, and is the largest of the gates at 830 metres. The name of the gate honours its builder, King Ludwig I of Bavaria.
Completed in 1840, the gate formed the entrance to the city and fortress from the north-west and west. There is a front gate in front of the Ludwig Gate, which is built from strong, red sandstone. Adjacent to the front gate is an armoury reduit as a line of defence.
The outer façade of the brickwork main gate was built according to the plans of the Munich architect Friedrich von Gärtner, King Ludwig I´s master builder. As you pass through, you can see two larger-than-life statues depicting knights, which, according to tradition, represent King Ludwig I, the builder of the fortress, and Knight Friedrich von Schmauß, the fortress´ construction manager.
Opposite the Ludwigstor you can see the Octroi House, which was used between 1843 and 1924 to collect the market money on the goods imported for the weekly market.
