in 1401 the council of one hundred (consell de cent), the former government of barcelona, decided to build the hospital de la santa creu merging and centralizing six hospitals in the city. the complex, designed by guillem d'abriell, was planned on a grand scale in the form of four two-story wings surrounding a central patio. the east wing (1406), north wing (1406-1509) and the west wing (1509) were built. in spite of the elapsed time they all have the same layout: ground floor covered with curved vaults that are very low with brick plates and upper floor with a double-sloped wooden beam on lightly pointed diaphragm arches. in front of the three wings the galleries of the cloister were arranged, with rib vault (begun in 1406 by guillem d'abriell).
