It served as a fortification for defence and is one of Munich's three remaining gothic town gates (the other two being the Isartor and the Karlstor).
As part of the great urban expansion by Ludwig the Bavarian (from 1285 to 1337), a second city wall with four town gates was built, of which Sendlinger Tor was one.
In 1318, Sendlinger Tor was first mentioned as a starting point for the road to Italy, but probably existed earlier.
In 1420 that was supplemented by the two flanking towers, which were required to terminate the end of the outer city wall properly.
It gives its name to the Sendlinger Tor U-Bahn, Tramway and bus station, one of the main interchanges within Munich’s systems of public transport.
