After four years of renovation work, the Santa Creu i Sant Pau Hospital and the rest of its modernist precinct was opened to public as a knowledge center and a new hub of historical, cultural and artistic interest for Barcelona's residents and visitors.The hospital is a small city within a city, endowed with an urban fabric of its own set on two cross axes rotated 45° off the orthogonal grid of the Eixample, as conceived by Idelfonso Cerdá. Although it was smaller than the original project, the old hospital included 27 wards, 16 of which were modernist. Six of them have now been renovated and two are in the process.
