When we get to Barcelona, we must come to this mountain to see it. We chose to take the subway to the Spanish Square and then take the bus from there. Mount Mongconk is not a mountain, but a small hillside. The car came down to the castle. Ticket 5 Euros, a castle can overlook the city's dense buildings, the distant Sacred Family Hall, and the more distant Sacred Heart Temple, as well as the farther mountains and snow peaks. On the other side of the castle you can see the endless Mediterranean Sea and the port of Barcelona. The castle itself is not very beautiful, but the city and the sea are worth seeing.
