One of the highest fortresses in the Apennines: a roofless 10th-century watchtower and ring walls on a bare limestone ridge at 1,460 m, free and open day and night.

Rocca Calascio began as a single square watchtower around the year 1000, built to signal across the Navelli plain and the Gran Sasso massif. The four round towers and curtain wall were added in the 15th century. An earthquake in 1703 emptied the settlement below; the castle was never restored for use and stands as a shell.

There is no gate, no ticket office and no roof. You walk in through a gap in the wall and look out over the Campo Imperatore plateau on one side and the Aterno valley on the other.

Why it stays quiet

It appears in several films, which brings people in July and August, but the site is a 2 km uphill walk at altitude with no facilities. At dawn or under snow it is usually empty.

Before you go

Free parking at the end of the road from Calascio. No water on site. Constant wind at the top; bring a layer even in August. Stargazing is exceptional.
