The Lion Monument in Lucerne , the most sentimental of Swiss Monuments, commerates the Swiss mercenaries who, serving the French King Louis XVI, lost their lives during the French Revolution at the Tuileries Palace in Paris . Many were killed during the invasion of the Tuileries on the 10th August 1792 while others were guillotined on the 2nd and 3rd September 1792. The inscription above the Lion reads "Helvetiorum fedei ac Virtuti" which translates as "To the loyalty and bravery of the Swiss." A fitting tribute.Carved into the cliff face, the monument measures a staggering 10 meters in length and and six meters in height. Captain Carl Pfyffer von Altishofen commissioned the Lion Monument which, in turn, was designed by the Danish classicist sculptor Bertel Thorvaldsen whilst in Rome in 1819. Lucas Ahorn, a stone-mason from Constance in modern day Germany, carved the sculpture out of the limestone cliff face in 1820 and 1821.
