Constructed in the Mudejar style, it is located on the edge of an extensive group of buildings, the Real Fábrica de Armas de Toledo (Royal Arms Factory) which was once one of the most important weapons factories in Spain, and is now the campus for the University of Castilla-La Mancha in Toledo. The tower was built to store water for us in tempering metalwork for swords and armour. It stood derelict for many years until it was restored for Tres Aguas, and now houses a vertiginous sculptural work offering a sequence of dramatic viewing experiences.

Visitors ascend an iron staircase on the exterior of the building to the roof from where they can enjoy exceptional views of the city and the river. They then descend a second staircase, drawn towards a large dark pool inside. Water flows over the sculpted forms, sometimes turbulently and sometimes more calmly, and then gradually drains away.

The cycle of movement inside the Torre del Agua lasts for 17 minutes.
