A tree-line promenade and the shore of Lake Zurich provide a perfect setting for the Sechseläutenplatz as seen here from the Quaibrücke bridge. It is Switzerland’s largest urban square at 19,000 square yards. It hosts several annual festivals, events and concerts. It’s also a wonderful place for a stroll or a lunch along the water’s edge. In the center is the Opernhaus Zürich.
