The former Hospital de la Santa Creu i Sant Pau in the neighborhood of El Guinardó, Barcelona, Catalonia, Spain, is a complex built between 1901 and 1930. It is one of the most prominent works of the Catalan modernisme architect Lluís Domènech i Montaner. The complex was listed as a Conjunto Histórico in 1978. Together with Palau de la Música Catalana, it was declared a UNESCO World Heritage Site in 1997.

Modernisme, also known as Catalan modernism and Catalan art nouveau, is the historiographic denomination given to an art and literature movement associated with the search of a new entitlement of Catalan culture, one of the most predominant cultures within Spain. Nowadays, it is considered a movement based on the cultural revindication of a Catalan identity. Its main form of expression was Modernista architecture, but it also encompassed many other arts, such as painting and sculpture, and especially the design and the decorative arts, which were particularly important, especially in their role as support to architecture. Modernisme was also a literary movement.
