During Barcelona's free time with group tours, we chose St. Paul's Hospital, the World Heritage Site, for medical work. It's easy to find a hospital by taking three stops on the subway next to Milla's house on Thanksgiving Avenue and walking for about five minutes. It's not cheap to visit 14 Euros, but it's worth seeing the hospital buildings full of artistic flavor. The whole hospital is a warm environment for patients. Art relieves patients'tension and anxiety. Underground passages connect ground buildings. The problem of cleaning and separation of pollutants has been solved scientifically. The reception hall of outpatient clinic is decorated like a museum. The murals on the exterior wall record the work of designers and builders. The end of the visit is just a sentence. I have never seen such a beautiful hospital before! ___________
