“The Rock of Guatapé” aka La Piedra is a massive rock located in the town and municipality of Guatapé, in Antioquia, Colombia.
The rock, which is almost entirely smooth with one long crack running top to bottom on one of the faces. Across this crack, is wedged a 649-step masonry staircase, that appears like a giant stitch holding the split rock together.
The rock was first scaled officially on July 1954 by three climbers using sticks embedded in the fissure on the rock. The staircase was built later.
