Biacis - Ahrensperg Castle and Saint James and Saint Anne Church

The hill where the small church of Saint James and Saint Anne stands was once the site of the Ahrensperg castle complex (Eagle Castle). The church's foundation is contemporary with the manor which it is annexed, but the current building dates back to 1520, with further restorations carried out in 1753.
The castle already existed during the Lombard age, cited in documents linking it to the events of the Castle of Saint John of Antro. A document from 1274 mentions the siege of the "new" castle of Ahrensperg, revealing the existence of two castles. The manor was also besieged by the Count of Gorizia in 1306, and in 1364 the patriarch ordered its definitive destruction.
The remains can be seen along the road that climbs from the village to the church: the foundations of a circular tower are visible, while next to the church there are the masonry structures of another quadrangular tower, partially restored, with slits on each side and a walled-up postern. Around the church, there is a stone wall believed to be part of the castle's enclosure wall; other remains of the fence emerge from the bush. On the hill, near the church, meetings of the Vicinia were held: under the porch of the small church, completely open on the right side, there was a stone slab (now placed at the entrance to the castle area) with symbols of an undetermined era engraved into it, around which the assemblies of the heads of families took place. The church is included in the “Cammino delle 44 chiesette votive” (Path of the 44 Votive Chapels) of the Natisone Valleys.
