On the upper floor of the building of the Llotja de Mar in Barcelona, is one of the key institutions in the cultural life of Catalonia in the 19th and early 20th century. The Real Academia Catalana de Belles Arts de Sant Jordi in Barcelona (Royal Academy of Fine Arts), was created in 1850 to oversee Catalan heritage and encourage the teaching of fine arts through the School of La Llotja. Now, no longer tied to its educational activities, it is focused on the dissemination of its art, archival and bibliographic collection.

Its art collection is made up of more than 700 paintings, 250 sculptures and various drawings and engravings by artists from the 16th century to the 20th century: from Annibale Carracci and Juan Ribalta to Modest Cuixart and Josep Maria Subirachs. Notable are the collections of drawings by Pau Milà i Fontanals and Lluís Rigalt. Above all, though, the Academy Museum offers a benchmark in Catalan art from the 18th-19th centuries, with paintings of Marià Fortuny and Ramon Martí Alsina, among others.

Many of the works come from the School of La Llotja. Others from convents and churches, or through donations or purchases. The bulk of the collection can be seen in the Llotja de Mar building, occupying the different rooms of the Academy, which have maintained their original appearance. Even so, some of its most outstanding pieces are on loan to the MNAC and other museums.

The Reial Acadèmia Catalana de Belles Arts de Sant Jordi also has an important library and an archive that brings together documentary material relating to the fine arts as well as photography.
