The castle preserves the two fundamental elements of medieval fortifications: the town walls and the citadel, which retains the keep. On the walls, which form an irregular polygon, the gates providing access to the old town are visible: the Sun Gate and the Azoia Gate.

A lagoon of approximately 1.3 km² with an elongated shape, formed by two main lagoon bodies connected by a narrow channel. Surrounded by vast sandy cliffs, this location has calm waters and serves as a refuge for migratory, aquatic, and wading birds. It is believed that this lagoon may have been the Tagus River's route to the sea, located 150 meters away. This fish spawning ground has protected dunes.

This space integrates a collection of archaeological remains of great importance for reconstructing the city's history. Here you can find traces from the medieval and modern periods, and even from the Roman era and the Iron Age.

The palace was built in the mid-16th century on the initiative of a local family called Furtado Mendonça, whose coat of arms can still be seen above the main door. The building has a Renaissance profile, evident in the design of the main portico and the fine arcade found in the inner courtyard. At the end of the 19th century, the palace was used as the headquarters of the Beja High School, a situation that lasted for 35 years. Currently, the building houses a student residence.

The Portas de Moura were rebuilt in 1867, when they were consecrated to Saint John the Baptist. At the top of the arch there is a passageway, decorated with a characteristic balcony.

Church of the former Franciscan Convent of Santa Clara, founded in the 15th century. At the end of the 19th and beginning of the 20th centuries, the city of Beja suffered extensive destruction of its heritage, and only the church, the cloister, the chapter house, and adjacent rooms survived from this former convent. The Gothic portal on the facade stands out, and inside, the gilded woodcarving and tilework are noteworthy. The Queen Dona Leonor Museum is now located within the convent.

A leisure area that includes gardens (water, scent, and color gardens), a central lake, infrastructure for a restaurant, kiosk and terrace, a designated dog racing track, a children's playground, and a small skate park. The space also features sports and recreational equipment geared towards sports and recreational activities.

According to tradition, this hermitage was founded by King Sancho I to commemorate the capture of Beja from the Moors in 1162. The ogival reconstruction, however, dates from the 15th century. It is part of the group of Gothic-Mudéjar constructions, typical of the Alentejo region, highlighting the narthex, the conical pinnacles and the battlements.

Possibly built between the 1st and 4th centuries AD, this arch is supported by two towers and is integrated into the medieval castle, outside the citadel. Also known as the "Évora Gate," its main function was to provide access to the barbican that surrounds the keep.

A village with artifacts dating back to the 1st century AD, containing traces of numerous quadrangular divisions of varying sizes arranged around an atrium.
