The Propylaea on Königsplatz in Munich was constructed in the middle of the 19th century by the architect Leo von Klenze as a symbol of the friendship between Bavaria and Greece and is based on the Propylaea of the Acropolis. In the form of a temple entrance, it initially served as a city gate, but today is located in the centre of Munich. On Königsplatz, the Propylaea has the Glyptothek on one side and the State Collection of Antiquities on the other. A cobbled street leads straight across the square and runs right up to the Propylaea. Königsplatz itself provides a lot of free space, some of which is used as a park or for open air events.
