Casalta is located at 464 metres above sea level and is part of the ancient parish of Ampugnani, in Castagniccia. This small village is built on a narrow rocky spur, to the south of Monte Sant'Anghjulu – its promontory overlooks the valley of Fium'Altu. It is a village surrounded by medium-sized mountains, an excellent starting point for several excursions. Indeed, all the villages in the Castagniccia are criss-crossed by hiking trails, shaded by centuries-old chestnut trees.

Casalta, like many villages in the region of Castagniccia, has a long history of craftsmanship. An iron factory, called a Ferreja, was built in 1857 by the Bastian entrepreneur Giovan Battista Casella. The factory closed at the beginning of the 20^th century, but until the 1960s this building was used as a hydraulic powered mill and fulling mill.

In Casalta you can run into the ruins of the chapel of St Mary (10^th century), which was the main church of the parish of Ampugnani, where the children were baptised. Today this chapel, which is located on a plateau full of olive trees, is completely invaded by a rich vegetation and until some time ago it was in danger of collapse. In 1993 the foundations of this chapel were reinforced, with the aim of protecting this Romanesque monument. In the hamlet of Costa a i Fiori you can find the ruins of a casa del vescovo, the residence of the bishops of Accia during the Middle Ages.
In the centre of the village you should visit the parish church of the Annunciation (17^th century), where a commemorative plaque dedicated to those who died for France is located on the façade of the main entrance.

This village is located at 44 km from Bastia, at 55 km from Aléria and at 61 km from Corte. Casalta is crossed by the D306 road.
