There are many tourists on the square, pay attention to safety! The Barcelona City Museum on the southeast side can be seen, and the church has not entered. The southwest side leads to the Cathedral of Barcelona, the north side of the square is the Grand Palace (Palau Reial Major), and the Gothic tower on the left is a good place overlooking the medieval city! When I was tired, I stopped to have a drink. My daughter was very active. My husband began to paint the Grand Palace.
