This is one of the most outstanding civil monuments in the city. It was built in stone by Juan de Flandes in the middle of the 16th century to replace an earlier construction called “Cañería de los Moros” dating from the 12th century. It was used to bring water to the city from the nearby mountain ranges of Cabezabellosa and El Torno and we currently conserve 55 arches, 7 of them next to the Hospital. It is 300 metres long and has a maximum height of 18 metres. Some of the arches were restored after their destruction in the Civil War.
