The building, constructed in Doric order, was completed by Leo von Klenze in 1862 and evokes the monumental entrance of the Propylaea for the Athenian Acropolis.
After King Ludwig I abdicated in 1848, the project was called into question, as, by that time, Munich no longer needed a city gate.
Finally, Ludwig I financed the building from his private resources as a symbol of the friendship between Greece and Bavaria, as well as a monument to the Greek War of Independence.
While on a visit to the Peloponnese in 1862, a coup was launched in Greece, a provisional Government was set up and a National Convention summoned .
The reliefs and sculptures celebrating the Bavarian prince and the Greek War of Independence were created by Ludwig Michael Schwanthaler.
