St. Paul's Hospital of the Saint Cross is the third World Heritage Site we visited in Barcelona and the second non-high cultural heritage. This is the first hospital to be listed in the World Cultural Heritage Site. What's the difference? Don't look, don't know. It's a real story. In the early morning of that day, we set out from the hotel on the north side of the Saint Family Hall, along the Avda de Gaudi, and came to the end of the Saint Cross Paul Hospital. The relationship between time and appearance can only be seen. Until June 2009, it had been used entirely as a hospital. Currently, it is mainly used as museums and cultural centers.
