Spring of los Cuatro Caños de Yuncler Monument · Yuncler, La Sagra, Toledo Image of Yuncler, not of the place itself. The Cuatro Caños fountain of Yuncler (Toledo), also known among residents as the Pilar fountain, was built in granite in 1700 and restored in 1889. It is fed by a spring located a few metres from the old road to Madrid, and it is one of the most characteristic historic features of the town centre.
