Castello Colonna is a historic fortified residence located in the town of Genazzano, originating from the 11th century. It served as a strategic stronghold for the Colonna family, one of the most powerful Roman noble dynasties. The structure has undergone significant architectural transformations over several centuries, shifting from a military fortification to a Renaissance noble residence. The internal courtyard features arcades and Renaissance elements reflecting the artistic tastes of the Colonna patrons. Historically, the castle hosted significant figures, including Pope Martin V, who was born into the Colonna lineage.
