The Giralda is a bell tower of the cathedral, which is one of the largest churches in the world.
The lower 2/3 of the tower was originally built as a minaret for the mosque in 1184 and at the time was the tallest tower in the world at 320 ft.
There are no steps. Instead there are 34 ramps, so that they could ride their horses up the tower to call people to prayer.
