Castelli_Stachilagi

This property is privately owned.

The castle was property of the Abbazia delle Tre Fontane and was named in the division of the County of Aldbrandesca in October 1216 among a list of important castles under Count Bonifazio. Purchased by Siena in 1409, its buildings were deteriorated by 1430 with only the central structures and keep left intact; by 1448 it would likely have been completely disarmed. Though some parts of the walls remain intact, much of the internal structure of the castle is in ruins.
