Monumental Roman bridge, built at the end of the 1st century AD, with a horizontal paved deck 117m long by 6.70m wide and a maximum height of 8.4m, consisting of six round arches, each with 33 identical voussoirs with a diameter of 8.95m per arch. The support is made of robust pillars resting on powerful foundations and a well-constructed system of niche-shaped openings and drains in the deck for safe water drainage in case of flooding. For about two thousand years, until the beginning of the 21st century, it served as a crossing over the Ribeira de Seda on the EN245. It was classified as a national monument in 1910 and is currently closed to traffic.

Located in the parish of Seda, in the heart of the Alentejo, the ruins of the walls that surrounded the ancient castle of Seda remain determined to preserve their ancient history. Without official evidence, some studies point to the existence of a castro of the Lusitanian tribe, occupied by Roman troops who would have erected a fortification there. The Roman presence in the region is well-known, and easily attested to by the Vila Formosa Bridge (1st and 2nd centuries), milestones, and the military road that would have connected Lisbon to Mérida. In 1160, King Afonso Henriques conquered the village, which at the time was called Arminho, from the Moors and donated the fortification to the Templars. This is the date that marked the beginning of the village's original enclosure. During the reign of King Afonso III, the village was handed over to the Order of Aviz and was later elevated to the status of a town, even serving as the municipal seat until 1836. The castle, however, gradually lost importance, and only a section of medieval wall, reinforced with turrets, has survived to this day. It has been classified as a Property of Public Interest since 1982.

Between walls and legends of tragic love, the fields around Flor da Rosa hold memories that can be felt at every step. The Monastery, founded in 1356 by D. Álvaro Pereira, stands out as one of the most unique examples of Portuguese Gothic: a fusion of fortress and temple, a living legacy of the Order of the Hospital.
