Giralda Tower: Soaring just over 300 feet high, the Tower began life as a minaret attached to the mosque, and serves now as a bell tower attached to the Cathedral. It is older than the church, dating from the 13th century, but has been much revised with the highest parts being added after the Cathedral’s completion. A wonderful view of the city can be obtained from the top, if you are energetic enough for the long upward trek (it is a winding ramp rather than a staircase). There is a modest admission charge for the Giralda, which also covers entrance to the Cathedral. Some parts of the Cathedral may require an additional fee.
