The Palace is the seat of the Paeria, the traditional name of the town council of this city. It dates back to the 13th century, although since then it has undergone many transformations. It was originally the residence of the Sanaüja family, lords of Borjas Blancas, who in 1383 ceded it to the Paeria to house the municipal government. It is also listed as an Asset of Cultural Interest.

Curiously, the Paeria is understood as the house of the "paer en cap". This term is used to refer to the mayors of the town councils of Lérida and Cervera. The term "paer" comes from the Latin word "patiarium", which means man of peace. This way of naming the mayors, in the case of the city of Lérida, is a privilege granted in 1264 by King James I to the former consuls of the city. In other words, the term "Paeria" designates the town councils of Lleida and Cervera.

The building is in the Catalan Gothic style. The façade contains all the most common elements of this school. At ground level, there is a doorway crowned by a half-circle arch that is reminiscent of Romanesque, since the typical Gothic point is missing, while on the first floor a series of tall, narrow windows return to the Romanesque theme with semicircles above and two slender columns each.

The windows on the first floor are very small and narrow, giving the palace a defensive appearance. Above the doorway are three coats of arms with the royal coat of arms; the middle one also has a royal crown.
