'The saddest and the most moving piece of rock in the world' according to Mark Twain, the Lion Monument was designed by the Danish sculptor Berthel Thorwaldsen and carved by Lukas Ahorn and is nothing but a heart-wrenching depiction of a dying lion. It commemorates the Swiss guards who lost their lives while defending Louis XVI of France during the French Revolution. The 'Lowendenkmal' is located in Denkmalstrasse, about a kilometre from the Chapel Bridge and perfectly walkable.
Standing tall above the Reuss River in the Old Town, the Kapellbruke has increasingly become the symbol of Lucerne, especially when it glows at twilight and makes for a pretty picture. This 14th Century water tower was completely destroyed by a massive fire in 1993 and had to be rebuilt. The panels on the roof of the oldest bridge in Europe contain paintings by Heinrich Wagmann depicting the glorious history of Switzerland. Make sure you cross this bridge when you get there.
