The Castle of Sant'Aniceto is a Byzantine castle built in the early 11th century on a hill in Motta San Giovanni, now in the province of Reggio Calabria, southern Italy.
It is one of the few examples of High Middle Ages architecture in Calabria, as well as one of the few well-preserved Byzantine fortifications in the world. The name derives from that of Saint Nikitas, a Byzantine admiral who lived in the 7th-8th centuries.
