Serpa Castle is part of the historic center. The fortification stands 230 meters above sea level and is an integral part of Serpa's walled structure, built by King Dinis.

A single-nave church preceded by a large galilee with a Mudejar-style finish, built in 1463 by the Duke of Beja (Infante D. Ferdinand) for the Xabregano friars. It was rebuilt during the reign of King Manuel. Notable are the recessed, coffered vaults of the galilee, chancel, cloister, and chapter house. Also note the unusual layout of the small cloister and the 17th-century tiles.

This military fortification existed since Roman times, but there is no record of its destruction or reconstruction. The current fortification of Serpa was built by King Dinis and consisted of a powerful castle and a double-towered wall. Significant sections of the wall remain, notably the one topped by a long aqueduct arcade, which extends to a monumental Moorish waterwheel. During the War of the Spanish Succession, the fortress suffered extensive damage. Of particular note are the Moura and Beja Gates and the imposing manor house of the Marquises of Ficalho.

A convent reflecting Manueline, Mannerist, and Baroque architecture. Its origins are Gothic, with notable highlights including the inscribed portal and triumphal arch. Baroque elements emerge in the decoration, especially in the ceiling painting.

The Guadiana area, north of Mértola, where the river narrows, and locals say you could cross from one bank to the other "in one leap." Wolves are also said to have frequently used this crossing. The "rapids," caused by the riverbanks compressing from 25 to 3 meters, are a key feature. Natural waterfalls are also common, the largest of which stands out at over 15 meters high. Access to the area is via a dirt road.
