The Fortress at position Tholi is located at the homonym region west of the Alagni village and dates back from the 16-17th century. The two-storey building, parts of which are still in bad shape, was protected by a wall.
Opposite the fort there is the double-aisled Church of the Holy Apostles and Saints Peter and Paul. This belonged to the Venetian family of Cornaro. It was built in the 15-16th century and still hosts two arcosoliums (tomb monuments) inside and outside the church (bearing the inscription 1614).
