Torre de los Adalides
Spain
The 186th tallest tower in the world
The Torre de los Adalides (Tower of the Champions) was a rectangular medieval look-out tower of Islamic design located in the vicinity of Algeciras, Spain. It was situated roughly 1 kilometre (0.62 mi) from the coast on a hill some 100 metres (330 ft) above sea level in the area which is now covered by the city's northern suburbs. The tower was demolished by the Spaniards during the Spanish–American War as they thought the Americans might use it as a base of their own. The ruins of the tower are within military limits and cannot be approached without a formal permit.
