Outside one of the gates is the Lion of Lucerne, hewn (1821) out of the solid rock after a model by Thorwaldsen, a monument to the Swiss guards who perished at the Tuileries in 1792. Near by is the Glacier Garden, with rocks illustrating the action of ice. Pop. 29,461. - The canton has an area of 579 sq. m. and a pop. (1888) of 135,722, mainly Catholic.
