Ponte de Vila Formosa

Ponte de Vila Formosa is a Roman bridge spanning the Seda stream with six round arches supported by rectangular stone pillars. The structure extends approximately 117 meters and continues to connect Alter do Chao with Ponte de Sor on its original route today.

The bridge was built between the first and second centuries and formed part of an important trade route connecting Lisbon with Merida in the Roman province of Lusitania. In 1910 the structure received the status of National Monument, officially recognizing its historical importance.

The bridge displays Roman construction methods that remain visible and show how Roman engineers designed river crossings for the ancient world. Visitors can still observe the carefully shaped stones and crafted details that highlight the importance of this connection in ancient times.

The bridge is located in Portalegre district in the Alentejo region and is easily reached via the main road between the two towns. Visitors can explore the structure from the road or walk along the stream to view the arches and pillars from different angles.

The bridge features decorative gargoyles along its railings and a half-moon carved detail in one of the main arches. These ornamental elements are unusual for bridges of that era and show that Romans integrated beauty into practical structures.
