It is one of the most emblematic spaces of the city surrounded by a magnificent setting of buildings from different eras and styles: the gothic Cathedral of Guarda, the Balconies Building, the old Council House, the Póvoas Manor House and the Alarcão Manor House.

Sabugal Archaeological Site corresponds to the ruins of Sabugal Velho and the remains cover the whole of the top of a small relief, indicating that Sabugal Velho is one of the fundamental archaeological sites for the study and understanding of the proto-history of Beira Interior and the Leonian presence in the lands of Riba-Côa. The settlement has been rehabilitated to be visited by the population and the materials from the archaeological campaigns are on display in the current Museu Municipal do Sabugal, and are one of its main attractions.

A Romanesque-style Catholic temple, it is thought to have been built between the 13th and 14th centuries and remodelled in the 16th century in order to adapt it to the functions required by the Santa Casa da Misericórdia. Built with a rectangular plan, single nave and lower and narrower chancel, it has a straight lintel window and a full arch inside.

A Cistercian monastery, it is a fine example of early Gothic architecture, with simplistic elements that well characterise the sobriety of the buildings occupied by the Cistercian Order. Although badly damaged by the French invasions, the church with baroque high altar still remains, with the monks' wing, the sacristy and the Chapter hall still preserved, a dining hall wall and the guesthouse building.
