"the most mournful and moving piece of stone in the world."
This is the Lion of Lucerne. The Latin inscription reads "To the Loyalty and Bravery of the Swiss". It commemorates the seven hundred Swiss Guards who stood their ground in the during the August Insurrection of the French Revolution and were massacred by the revolutionaries.
Mark Twain had this to say about the Lion: "The Lion lies in his lair in the perpendicular face of a low cliff — for he is carved from the living rock of the cliff. […] The place is a sheltered, reposeful woodland nook, remote from noise and stir and confusion — and all this is fitting, for lions do die in such places, and not on granite pedestals in public squares fenced with fancy iron railings. The Lion of Lucerne would be impressive anywhere, but nowhere so impressive as where he is."
