Castel del Monte

Castel del Monte is famous for its eight-sided plan, eight octagonal towers, and unusually geometric design. The exact symbolic meaning is debated, but the layout is a major reason UNESCO listed it as a World Heritage Site in 1996.

It was built under Frederick II, the Holy Roman Emperor who ruled Sicily and much of southern Italy in the 13th century. The castle stands in Apulia near Andria, away from the dense urban centers of the region.

It has castle features, but it lacks some practical defensive elements found in more conventional medieval fortresses. Many visitors search for it because it feels part fortress, part hunting lodge, and part imperial symbol.

Castel del Monte appears on Italy's 1 cent euro coin. Its selection reflects its status as one of Italy's most recognizable medieval monuments and a UNESCO site.
