The Hospital de la Santa Creu is a medieval hospital that reads books now. Its long upper wards, built to hold the sick of Barcelona, are the reading rooms of the National Library of Catalonia: rows of desks and shelving under high timber ceilings, with the Gothic structure untouched overhead. Below them, stone vaults on wide arches carry the whole thing. At the centre is a Gothic courtyard with an arcade around it, open all day and one of the quietest places in the quarter.
The hospital treated patients here for five hundred years, from 1414 until it closed in 1926 — the year Antoni Gaudí was carried in from a tram accident and died in one of its rooms. Its foundation stone had gone down in 1401 with the king present, and it grew by stages into the largest hospital in Catalonia. The library moved into the wards in 1939. Around the same courtyard stand the Institute for Catalan Studies, in the old convalescent house, and the Royal Academy of Medicine, which keeps an eighteenth-century anatomical theatre.
