The Palau de la Música Catalana and the Hospital de la Santa Creu i de Sant Pau, works of the architect Lluís Domènech i Montaner, are two emblematic buildings of Catalan modernista architecture. Located in the city of Barcelona, they were built in the early years of the 20th century and have been on the Unesco World Heritage list since 1997.

The two buildings are good examples of modernista architecture, an artistic movement that arose in Europe in the late 19th century and which, in Catalonia, and especially in Barcelona, became widespread.

Both the Palau de la Música Catalana and the Hospital de la Santa Creu i de Sant Pau are public buildings in which tradition and modernity are fused together. They show a significant renewal of traditional techniques and the incorporation of new architectural solutions. To their architectural value is added beauty and decorative exuberance, becoming works of universal artistic and historical significance.

These constructions masterfully display the essence of modernisme and the period in which they were built: beyond the artistic side, he represented an ideological movement, based on the modernisation of the country and the search for an identity in a historical context in which civil society, especially the bourgeoisie, became the most loyal sponsor.
