The castle includes the ancient church and the “spedale” (hotel) for the pilgrims in transit to Rome on the Via Francigena.
In 1979 it was acquired by Count Marcello Alberto Cristofani della Magione, who donated it to the Militia Templi, which was just being founded, as the Magistral See.
The castle maintains signs of its Romanesque origins, in spite of some changes made during the ensuing centuries.
In the courtyard, visitors will see the premises of the convent for the Knights, the small guest-rooms and the flight of steps for access to the upper floor.
The Magistral Church of San Giovanni in Jerusalem is designed in a pure Romanesque style, as it can be seen from the altar.
