AI overview
I don't have sufficient context to write an accurate 2-sentence overview. While I know Castelseprio is an Italian comune (municipality), the single-word descriptor doesn't tell me what makes it notable or why it matters historically, culturally, or otherwise. Without reliable details about its significance, I cannot create an accurate overview for a general reader.

Castelseprio is a comune (municipality) in the Province of Varese in the Italian region Lombardy, located about 35 kilometres (22 mi) northwest of Milan and about 11 kilometres (7 mi) south of Varese, bordering the municipalities of Cairate, Carnago, Gornate-Olona and Lonate Ceppino.
The main centre, formerly known as Vico Seprio (a name still in informal local use) is near the historically significant ruins of the ancient and medieval city of Castelseprio, which are today in an archaeological zone open to the public at the normal hours. The site is most famous for the Byzantinesque frescos in the small Church of Santa Maria foris portas, a UNESCO World Heritage Site since 2011.
