What is Wells of Toledo?

Before the standardization of modern plumbing, 2 common ways existed to access water in Toledo, Spain. These include the Tagus river that runs alongside the city, water wells and water reservoirs. Water wells and reservoirs were generally placed inside the city centre, or in some cases, individual housing. They were generally denoted by a water well or reservoir indicator. Generally the indicators consisted of small stone balls. In cases of a fire, the public would know who had a water well or reservoir. Many streets that had these wells/reservoirs were entitled as such, with many sharing the name "Well Street".
