Abbey of the Holy Spirit at Monte Morrone, Sulmona

The Abbey of the Holy Spirit at Morrone (Italian: Abbazia di Santo Spirito al Morrone), locally Badia Morronese is a former Celestine monastery founded in the late 13th-century by the hermit Pietro da Morrone. The complex stands at the foot of Monte Morrone, about 5 km (3 mi) north-east of Sulmona, in the Province of L'Aquila, Abruzzo, Italy.

After the suppression of the Celestine Order in 1806, the abbey passed to the state; it now houses the offices of the Soprintendenza Archeologia, Belle Arti e Paesaggio per l'Abruzzo and a small archaeological museum. Much of the visible fabric reflects 17th- and 18th-century Baroque remodelling.
