john rains house and rancho cucamonga-area history

In the heart of Rancho Cucamonga stands the María Merced Williams and John Rains House, a testament to the region's rich history.

Constructed in 1860, this historic residence was built using bricks made from the site's red clay, with a roof waterproofed by tar sourced from the Brea Pits in Los Angeles.

After purchasing the Rancho Cucamonga land grant in 1858, John Rains and his wife, María Merced Williams, moved into the house in the spring of 1861 with their three children.

Rains established what is believed to be California's first commercial winery, hosting lavish parties that cemented the home's reputation for hospitality.

Located at 8810 Hemlock Street, the house was added to the National Register of Historic Places in 1973 and is now part of the San Bernardino County Museum system.

In June 2022, the San Bernardino County Board of Supervisors voted to rename the historic site to honor both María Merced Williams and John Rains.

On April 27, 2024, a ribbon-cutting ceremony celebrated recent improvements to the house, attended by local officials and community members.

Today, the site is open to the public from 10 a.m. to 3 p.m., Tuesday through Saturday, offering free admission.

Visitors can explore the house's rich history and its role in the development of Rancho Cucamonga.

Rancho Cucamonga's history dates back to the early 19th century when Tiburcio Tapia was granted 13,000 acres in 1839, establishing the area's first winery.

The region's name is derived from a Native American word meaning "sandy place," reflecting its indigenous heritage.

Over the years, the area evolved from agricultural roots to a vibrant community, incorporating as the city of Rancho Cucamonga in 1977.

Today, it stands as a testament to the blending of its rich past with modern development.
