The building, situated next to the Cathedral of the Holy Cross and Saint Eulalia, has a long tradition as accommodation for high-ranking church officials. In fact, this structure already served as lodging for two previous pontiffs during their visits to the city, specifically in 1982 and 2010.

The Episcopal Palace, also known as Palau del Bisbe, is a property protected as a Local Cultural Heritage Asset. Its structure is a testament to the city's history, as it stands on the ancient Roman walls and remains of a 5th-century domus. Archaeological excavations have revealed that the subsoil preserves vestiges of Roman facilities, such as a fish salting factory and a winery.

Architecturally, the building is a compendium of styles ranging from Romanesque to Neoclassicism. While the interior gallery preserves 12th-century arches, the windows are 14th-century Gothic, and the exterior facade was remodeled following neoclassical canons during the 18th century.

Currently, the palace not only functions as a residence but also serves as the headquarters of the Diocesan Archive and a cultural space that hosts exhibitions and collections of religious art documenting the history of Catalonia.
