The castle of Montalto lies east of Siena, Italy, in an area known as ‘la Berardenga’, which is an extensive territory in the Chianti region of Tuscany. Its position right on the border between the territories of Siena and Florence gave it great strategic importance during the 13th, 14th and 15th centuries. Much of the castle is from medieval times and parts date back to 1000 or earlier; extensive restorations were performed in the 16th century and again in the 19th century.
Montalto stands on a hill overlooking the upper . An entry archway surmounted by a turret leads into a courtyard with a well. To the right is the church of San Martino, and a fresco on the inside of the entry tower depicts the famous scene of the saint sharing his cloak with a beggar. To the left is a loggia with four arches from which one has access to the main villa and the Sala d’Armi (Hall of Arms) with its large fireplace and collection of lances, armor and weapons dating from the 14th century onward. The upper portion of the walls in the Sala d’Armi is decorated with frescoes depicting famhouses belonging to the castle in the 16th century and vignettes of every-day activities on the land of the Berardenga (hunting, farming, etc.).
The watchtower has loop-holes and ramparts which hint to the castle’s past as a stronghold on the highly contested border between the rivaling towns of Siena and Florence.
The complex includes six other buildings and is surrounded by a wall of stone and brick attesting to repeated war damage and reconstructions. Ground fill within the wall circle brings ground level to within 1 meter of the top of the wall on the inner side.
