Palacio in Madrid, Spain — Southwestern Europe (Iberian Peninsula)
Los Caños del Peral
El manantial que abastecia a la fuente fue aprovechado en época medieval por una población asentada en torno a una de las puertas de la muralla cristiana, la puerta de Balnadu.
Mencionadas en los documentos historicos desde el siglo XVI, la fuente y la plazuela donde se ubicaba, cobran singular importancia para una poblacion en creciente aumento. Este espacio urbano fue objeto de numerosas reformas hasta la primera mitad del siglo XIX, momento en el que quedo sepultado por tierras y escombros.
Las obras de reforma promovidas por metro de madrid han permitido recuperar parte del antiguo entramado urbano e integrarlo en la nueva Estacion de Opera.
In this same spot, eight meters underground, lies the Canos del Peral fountain, a monumental public fountain in the Renaissance style, built during the reign of Philip II for the adornment and use of this town.
The spring that fed the fountain was used in medieval times by a population settled around one of the gates of the Christian wall, the Balnadu Gate.
Mentioned in historical documents since the 16th century, the fountain and the small square where it was located held particular importance for a rapidly growing population. This urban space underwent numerous renovations until the first half of the 19th century, at which point it was buried under earth and rubble.
The renovation works undertaken by Metro de Madrid have allowed for the recovery of part of the old urban fabric and its integration into the new Opera Station.

The Fountain of the Pear Tree Canals (Spanish: Fuente de los Caños del Peral) is an ancient fountain discovered buried under the Plaza de Isabel II in Madrid, Spain, in 2009. The name comes from a 13th-century pear tree that shaded the source spring at the fountain's location. The fountain is also known as the Spanish: Lavadero de los Caños del Peral (Laundry of the Pear Tree Canals).(Submitted on November 29, 2025.)
