Fountain of the Pear Tree Canals

The fountain is also known as the Spanish: Lavadero de los Caños del Peral (Laundry of the Pear Tree Canals).

The discovered part was built in the 17th century and was originally 34 m (112 ft) in length, occupying a small valley at the end of Arenal Street.

[2] Work began on reconditioning the Ópera Metro station that served the Teatro Real and the two plazas in 2009, which led to the rediscovery of the fountain.

[2] The museum showcases the fountain of the canals along with other relics found at the site, such as the original parts of the Arenal Sewer, and the royal Amaniel Aqueduct.

[1] The museum, accessed from the lobby of the Ópera station, is 200 m2 (2,200 sq ft) in size and free to anyone with a metro ticket.
