The church of Santa Maria foris portas contains some of the oldest and most important cycle of frescoes from the Early Middle Ages, executed in a sophisticated Byzantine style.
The archaeological site was largely abandoned after its destruction in 1287, leaving its medieval layout relatively undisturbed by later urban development.
Excavations revealed a sophisticated defensive system including a double wall structure and a gatehouse dating back to the 5th and 6th centuries.
The site was a key strategic stronghold for the Longobards, who utilized the preexisting Roman foundations to control the transit routes between Como and Milan.
The 'Antiquarium' museum is housed in a restored 14th-century building and exhibits material from the site, including Roman funeral steles and medieval pottery.
Castelseprio Archaeological Park is a UNESCO World Heritage site located in the Lombardy region, famous for housing the rare Byzantine frescoes in the Church of Santa Maria foris portas. The site spans the remains of a significant medieval fortified village (castrum) that was destroyed in 1287 by Ottone Visconti. Visitors can explore the ruins of the defensive walls, the Basilica of San Giovanni Evangelista, and the Antiquarium museum which displays artifacts recovered during 20th-century excavations. The park offers an elevated vantage point over the Olona Valley, showcasing both Roman and Longobard structural layers. It is part of the 'Longobards in Italy: Places of Power' serial site.
