The Blue Holy Week Museum, widely known by the acronym MASS, is an impressive cultural space located in the city of Lorca. As the largest museum in the Murcia region, it occupies over 3,500 square meters within the walls of a restored 16th-century Franciscan monastery. It is a place where centuries of history meet modern exhibition art.

The museum serves as the primary home for the treasures of the Brotherhood of Labradores (Paso Azul). It houses a unique collection of sacred vestments and robes, embroidered with silk and gold, used in the famous processions of Spain. The exceptional value of the collection is highlighted by the fact that six textile pieces hold the status of Assets of Cultural Interest (BIC)—the only embroidered works in the country with this title.
The museum's main feature is its dedication to preserving Lorca embroidery, which is a candidate for the UNESCO Intangible Cultural Heritage list. Visitors can expect more than just a fabric exhibition; it is an immersion into an atmosphere of celebration, faith, and incredible human talent.
