At the center of the city is the Marienplatz - a large open square named after the Mariensule, a Marian column in its centre - with the Old and the New Town Hall. Its tower contains the Rathaus-Glockenspiel, an ornate clock with almost life-sized moving figures that show scenes from a medieval jousting tournament as well as a performance of the famous "Schfflertanz" (roughly translated "Barrel-makers' dance"). Three gates of the demolished medieval fortification have survived to this day - the Isartor in the east, the Sendlinger Tor in the south and the Karlstor in the west of the inner city. The Karlstor is the oldest building at Stachus, a grand square dominated by the Justizpalast (Palace of Justice).
