"Vandals have damaged Peru's famous 12-cornered Inca stone in the Andean tourist city of Cusco by scarring it with a sharp metal object. The stone, which is both a national symbol and one of Cusco's best-known tourist sites, was damaged on Thursday night with either a nail, a screwdriver or a chisel.

The stone has a scar which is 15 centimeters (6 inches) long and 4 centimeters (1.6 inches) wide, and can not be repaired because officials could not find the shards the vandals chopped off.

...The large gray stone, a product of Inca craftsmanship thought to have energizing properties, is part of an outside wall in the palace of Cusco's archbishop and is on permanent display, unprotected by glass or plastic."

Hopefully this will prompt officials worldwide to better protect such relics...
