Zeuthen

It is located near the southeastern Berlin city limits on the western shore of the Dahme River and the Zeuthener See. It borders Eichwalde in the north, Schulzendorf and Schönefeld in the west, Wildau and Königs Wusterhausen in the south, as well as the Berlin borough of Treptow-Köpenick on the eastern shore of Zeuthener See, where the municipal area also includes the Miersdorfer Werder exclave. The four municipalities of Zeuthen, Eichwalde, Wildau and Schulzendorf form a coherently built-up suburban area.
Probably of Slavic origin like many Brandenburg settlements, Zeuthen with neighbouring Miersdorf and Gersdorf was first mentioned in the 1375 Landbuch written at the behest of the Luxembourg emperor Charles IV, who had acquired the margraviate from the Bavarian House of Wittelsbach two years before.
