Take the subway L1 and L3 and get off at Espanya station. There is an escalator on Mount Moncone behind the Spanish Square. The museum is divided into two floors, the first floor is mainly about religion, and the second floor is more artistic. Photographs can be taken in the pavilion. It's free after 3 p.m. on Saturdays. Two hours is enough for a tour. In front of the National Museum, you can overlook the Spanish Square and some urban landscapes. The scenery is still good.
