In the distant shot of Seville, the Gold Tower is shown to be part of the city walls. In reality, the Tower was a separate structure connected to the wall by a smaller, one-way wall, whose purpose was to blockade the river to enemy shipping (the city walls proper were farther from the river than they are in the show). The Tower in the shot also has the three stages completed, but the third with a golden cupula was built only in the 18th century.
