All those who have some interest in Barcelona probably know two names for sure: Lionel Messi and Antoni Gaudi. Messi plays for Barcelona Football Club and Gaudi designed the church of Sagrada Familia. Barcelona FC cannot be seen in action every day, but the Sagrada Familia is open on all days. You need to get a ticket, and then come in the exact 15 minutes that your ticket says you have to enter. After that it is a mad rush through this church. Can you help it?
