The Porta de Marvão is a medieval gate in the fortified town of Marvão, which serves as the main entrance to the village. The town is perched atop the Serra de Sao Mamede mountains and offers panoramic views of the surrounding Alentejo region. Marvão's narrow streets are lined with whitewashed houses with Gothic arches and Manueline doorways. The well-preserved 13th-century castle is a focal point, giving visitors a glimpse into the town's rich history and strategic importance.
The Porta de Rodão was built much later, in the 17th century, to reinforce defenses during the War of Independence against Spain in the mid-17th century. There is a small parking lot in front of it. Due to the narrow streets and almost complete lack of parking, driving through the gate into Marvão is strongly discouraged.
Another fortified gate, providing pedestrian access to Vila Marvão, is located to the east. This is also worth a visit.
