As a result of the confiscations in the 19th century, a large part of the artistic heritage of the church was dispersed or privatised.With the Catalan Renaixença (Catalonia's cultural renaissance) efforts were made to recover and protect this entire legacy through initiatives such as the Museu de Lleida Diocesà i Comarcal, (Diocesan and Regional Museum of Lleida), founded in 1893, following the example of the Museu Episcopal de Vic. Today, the museum manages an important artistic legacy from the lands of the West and from the ancient Diocese of Lleida, which covers the period from prehistory to the modern age.
In 2007 the new branch was opened that set out the criteria of the site.There are certain outstanding exhibits that must not be missed during the tour of the museum. These include the head of a Roman satyr, altar frontals from the 13th century and sculptural fragments of the Seu Vella. From the Renaissance and Baroque, works by the painter Pere Nunyes, sculptures by Gabriel Joly and Damià Forment and several works by the painter Antonio Viladomat.
Highlights of the permanent collection include two unique pieces: the chess game of 10th -11th century by Sant Pere d’Àger and the Mare de Déu de Bellpuig de les Avellanes, one of the most important examples of Catalan Gothic heritage
