Piedra Movediza (lit. 'Moving stone') was a balancing rock located in Tandil, Buenos Aires Province, Argentina. Its weight was about 300 tons. It attracted attention and tourists because of the way it was balanced on the edge of a hill.^[1] The stone fell and broke on 29 February 1912. Some sources say it fell due to vandalism or vibrations caused by explosions in a nearby quarry.^{[citation needed]}
