The most significant part of a large necropolis from the Roman and late Roman period, above which a small chapel dedicated to Saint Sebastian was implanted in the XVI century, was excavated in the secondary school playground and turned into a museum.

The cemetery excavated in the rock can be visited via a small metallic walkway and has an explanatory notice board. The hermitage that was completely reconstructed in a pedagogic operation with the help of the archaeology students from the Bento de Jesus Caraça School, houses a small on site museum where amongst other artefacts a gold Chrisma medallion from the V century found in a child’s tomb can be admired.
