Castelseprio

Castelseprio was the site of a Roman fort in antiquity, and a significant Lombard town in the early Middle Ages, before being destroyed and abandoned in 1287. It is today preserved as an archaeological park in the modern comune of Castelseprio, near the modern village of the same name. It is in the north of Italy, in the Province of Varese, about 50 km northwest of Milan.

The fame of Castelseprio lies in the Early Medieval frescoes contained in the apse of the small Church of Santa Maria foris portas, which were only rediscovered in 1944. These frescoes are of exceptional rarity and artistic significance, and show strong Byzantine influence. The dating of the frescoes and the origin of their painter or painters remain controversial, although the first half of the 9th century seems to be emerging as the most likely date.
