The María Merced Williams and John Rains House, built in 1860, has a history as colorful as the property’s gardens. Namesakes Rains and Merced, granddaughter of the prominent landowner Don Antonio Maria Lugo, built the home to withstand the hot inland Southern California climate, and of course to entertain. The home featured multiple large rooms and guest quarters as well as an open flume that carried water from springs through the kitchen and into the patio under the house to the orchard, providing water to the plants and cooling the home.

The María Merced Williams and John Rains House is located at 8810 Hemlock Street, at the Vineyard Avenue exit from Interstate 10 in Rancho Cucamonga. The historic site is open Tuesdays through Saturdays from 10 a.m. to 3 p.m. Admission is free to the public.

The San Bernardino County Museum’s exhibits of regional, cultural and natural history and the Museum’s other exciting events and programs reflect the effort by the Board of Supervisors to achieve the Countywide Vision by celebrating arts, culture, and education in the county, creating quality of life for residents and visitors.
