Rocca di Calascio, at an elevation of 1,460 m, is the highest fortress in Italy located in the province of L’Aquila. It was exclusively built for military purposes and intended only to accommodate troops. The fortress was started in the 10th century as a single citadel watchtower. It was badly damaged in 1703 by an earthquake. Near the fortress, at a slightly lower elevation, is Santa Maria della Pieta, an octagonal church built in the 17th century.
