Domènech i Montaner outdid himself as architect and philanthropist with this Modernista masterpiece, long considered one of the city’s most important hospitals. The complex, including 16 pavilions – together with the Palau de la Música Catalana, a joint World Heritage Site – is lavishly decorated and each pavilion is unique.

Domènech i Montaner wanted to create a unique environment that would also cheer up patients. Among artists who contributed statuary, ceramics and artwork was the prolific Eusebi Arnau. The hospital facilities have been transferred to a new complex on the premises, freeing up the century-old structures, which are being restored to their former glory in a plan to convert the complex into an international centre on the Mediterranean.

Guided tours are the only way the curious get inside this unique site – but the building might one day open up for more regular visits.
