Framing the Novohispanic House or House of the Aqueduct, is the construction that gives this space its name. The double-arched aqueduct from the 17th century supplied water to the ponds, lavabos, kitchen, and the “secret room” or latrines, all fed by springs from San Bartolomé Ameyalco. The water from the Magdalena River was only used for irrigating the orchard, as it was somewhat contaminated due to passing through the mills, fulling mills, and factories upstream.
