The former Hospital de la Santa Creu i Sant Pau in Barcelona was built to plans by Lluís Domènech I Montaner between 1901 and 1930. Composed of many independent pavilions, it is the world's largest complex built in Art Nouveau style. After being closed as a hospital in 2009, it was renovated and re-opened as a museum and cultural center in 2014.
Surrounded by gardens, 12 of the pavilions are connected through 1 km of underground corridors. The Hipostyle Hall is characterized by its large brick columns and ceramic tiles.
Each pavilion was used by a different medical specialty. The design emphasized the importance of natural light and ventilation in the treatment of patients. Ceramic tiling was used extensively in order to ensure hygiene.
The administrative pavilion served as the main access point to the hospital site.

It is also one of the first non-industrial buildings to use exposed brickwork on its inside.
The Lluís Domènech i Montaner Hall is located in the center of the administrative pavilion on the first floor. Two brick arches divide the room in three sections.
A balcony is present on three sides of the room. Its stone tracery in Gothic letters reads "Ampareu Syor als benefactors y als asilats d’aquesta santa casa aixís en la terra com en lo cel e inspireu sentiments de caritat envers d’ella amen." The 2.5 meters by 6.8 meters large painting "Translación de los restos mortales de santa Eulalia de Santa María del Mar a la catedral de Barcelona" by Aleix Clapés can be seen on one of its walls.
