The Tomb of Caecilia Metella stands as one of the most remarkable ancient monuments along the Appian Way. Built for Caecilia Metella, who died in 69 BC, this structure has endured through centuries and remains well-preserved, its massive stone form commanding the views of the surrounding landscape.
During the Middle Ages, the mausoleum underwent a significant transformation. It was converted into a fortress, and battlements were added to its upper sections. This change reflected the turbulent times, when powerful families competed fiercely for control of the building. Its strategic position along the Appian Way made the tomb an important stronghold, as well as a symbol of influence in the region.
