Seville's Tower of Gold (Torre del Oro), undoubtedly one of the most iconic landmarks of the city, has guarded Seville since its construction in the 13th century. Built as a watchtower in the Almohad dynasty, through the centuries, the Tower of Gold has been used as a chapel, a prison, a lookout point and a gunpowder store. Climbing the tower is a must-do activity for any visit to Seville. From the top, you can look out for a spectacular view of the river and of the Triana neighborhood. Getting its name from the golden hue its high walls project on the river below, make sure to take a stroll around the base of the tower after you climb to the top!
