The last Roman villa standing: Legend has it that the ruined building at São Cucufate in the Alentejo region was thought to be just another old farmhouse until an archeologist drove by and realized it was a Roman villa. Though hundreds of these villas had once dotted southern Portugal, finding one still intact is a rare thing. The ruins include a tank that was once a swimming pool, and hot- and cold-water public baths. The main building, flanked by two turrets, was occupied throughout the centuries. During the middle ages, a monastery was founded here, dedicated to St. Cucufate.
A mysterious Roman ruin that defies definition can be seen near the town Belmonte. Here, in the mountains of the Centro Region is the Centrum Cellas, a three-story ruin that may have been a watch tower, but no one knows for sure.
A single arch from a once great Roman building stands in the town of Bobadela in the Centro region.
