Masso Gastaldi, Glacial erratic in Pianezza, Piedmont, Italy.
The Masso Gastaldi measures 26 meters in length, 16 meters in width, and 14 meters in height, with a total volume of 2000 cubic meters.
During the Mindel glaciation period, this large boulder was transported to its current location by glacial movement through the Susa Valley after a landslide.
The stone features a chapel dedicated to Archangel Michael at its summit, replacing an older religious structure that once stood in the same location.
Visitors can access the summit by contacting the Italian Alpine Club section of Pianezza, which maintains the site and organizes guided tours.
The rock formation houses a World War II air raid shelter beneath its structure, which reopened to the public in 2016 after extensive restoration.
