For a bird’s-eye view over Lucerne’s rooftops to the glittering lake and mountains beyond, wander the medieval ramparts. A walkway is open between the Schirmerturm (tower), where you enter, and the Wachturm, from where you have to retrace your steps. You can also ascend and descend the Zytturm or Männliturm (the latter not connected to the ramparts walkway).
