The tower was badly damaged by the Lisbon earthquake of 1755, and the Marquis of Monte Real proposed demolishing it to widen the way for horse-drawn coaches and straighten access to the bridge of Triana; however, the people of Seville objected and appealed to the king, who intervened. In 1760, the damage was repaired, with repairs to the bottom floor of the tower, reinforcement with rubble and mortar, and the creation of a new main access via the passageway to the path around the wall. That same year, the upper cylindrical body was built, a work of the military engineer Sebastian Van der Borcht, also architect of the Royal Tobacco Factory of Seville. These works changed the appearance of the tower as compared to what is seen in engravings from the sixteenth or seventeenth centuries.
