The Brandenburg Gate on the Luisenplatz in Potsdam, not to be confused with the gate of the same name on Berlin's Pariser Platz, was built in 1770/71 by Carl von Gontard and Georg Christian Unger by order of Frederick II of Prussia. It stands at the western end of Brandenburger Straße, which runs in a straight line up to the Church of St. Peter and St. Paul.
Previously, from 1733, there was another, simpler gate on the same spot, which resembled a castle gateway. Together with the city wall, a form of toll or excise barrier, and the other gates it was intended to prevent desertion and smuggling.
