San Gabriel, California: the 1771 mission that named the valley, three surviving adobes, the Mission Playhouse, and the deepest architectural record in the San Gabriel Valley.
The valley is named for this town’s church. San Gabriel is a city in the western San Gabriel Valley of Los Angeles County, California, built around Mission San Gabriel Arcangel, the fourth of California’s twenty one missions, founded in 1771. The mission’s stone church is the oldest brick, stone, and mortar building in Southern California, and the small city around it holds the longest architectural record in the valley: three surviving adobes, a rail era town core, a 1920s civic ensemble in the Spanish revival styles, and quiet neighborhoods that filled in through the postwar years. San Gabriel gave the valley its name and its founding style vocabulary.
Mission San Gabriel Arcangel was founded on September 8, 1771 by Fathers Pedro Benito Cambon and Angel Fernandez de la Somera, the fourth of California’s twenty one missions. The first site near the Whittier Narrows flooded, and the mission moved to its present ground in 1775. The stone church that stands today was begun in 1791 and completed in 1805 under Father Antonio Cruzado of Cordoba, Spain. Cruzado gave it capped buttresses and tall narrow windows found nowhere else in the mission chain, borrowed from the cathedral of Cordoba, a former mosque. The result reads more like a fortress than a chapel (California Historical Landmark No. 158; National Register of Historic Places No. 71000158, listed 1971).
The honest record stands beside the romantic one. The church rose on the Tongva village site of Toviscanga, built with Tongva labor the National Park Service describes as forced, and about six thousand Tongva people are buried in its cemetery. A Tongva woman named Toypurina helped lead a rebellion attempt here in 1785. In 1781 the pobladores walked nine miles from this mission to found Los Angeles, the reason San Gabriel is called the birthplace of the Los Angeles region, and that walk is still reenacted every year.
On July 11, 2020, an arson fire took the roof and choir loft just before the mission’s 250th anniversary. The restoration worked from measured drawings, historic photographs, and paint samples, returned the sanctuary ceiling to stained redwood, and reopened the church and museum on July 1, 2023. The Los Angeles Conservancy gave the project a 2025 Preservation Award. I built custom homes for twenty years and I judge restoration work by its discipline. A rebuild that starts from measured drawings and paint archaeology instead of guesswork is the standard every period project should meet.
When the 1920s boom went looking for a California identity, San Gabriel already owned the original, and the city answered with a civic ensemble in the revival styles, the story told in full in The Spanish Revival Wave. City Hall went up in 1923 in the Spanish Colonial Revival style, on a site donated in 1922 by Walter P. Temple, the man then founding Temple City four miles east. The Arcade Building of 1922 carried Mission Revival storefronts. The Bank of San Gabriel, 1915, wore Spanish Colonial Revival a decade early.
The jewel is the Mission Playhouse, built 1923 to 1927 and dedicated on March 5, 1927 to house John Steven McGroarty’s Mission Play. Arthur Burnett Benton designed it in the Mission Revival style, with its facade modeled on Mission San Antonio de Padua, and William J. Dodd finished and reshaped the building after Benton’s health failed. Inside are 1,387 seats, a carved and painted ceiling, and tapestries given by King Alfonso XIII of Spain. The play ran 3,198 performances and drew about two and a half million people before closing in 1932. The city bought the building in 1945, ran it for decades as the Civic Auditorium, restored the original name in 2007, and saw it listed on the National Register in 2019. Beside it, the Grapevine Arbor shelters an offspring of the 1861 Mother Vine, a living cutting of the mission stock that once supplied one of the largest wineries in the world.
Three adobes still stand. The Rancho Las Tunas Adobe’s first rooms are said to date to the 1770s, raised for the mission’s friars, which would make it the oldest house in the county. The Lopez de Lowther Adobe was built between 1792 and 1806 and stayed in one family’s use into the 1960s. The Ortega-Vigare Adobe dates to the same years, 1792 to 1805. Las Tunas Drive carries the name of the prickly pear, las tunas, from the cactus hedge that once ringed the little rancho beside the mission.
The town around them grew in layers. By the 1880s San Gabriel was a rough rail stop, a place the county library’s history describes as a wild little town with eighteen saloons in two blocks, and the residents voted the saloons out in the early 1890s. The city incorporated on April 24, 1913 with about 1,500 people. The city’s own historic context statement dates the earliest surviving buildings to the 1775 mission relocation and marks the character of today’s neighborhoods as set between the 1920s boom and the postwar buildout.
San Gabriel takes its old buildings seriously, and a buyer here inherits that. The city adopted a historic preservation ordinance in 1965, the second city in Los Angeles County to do so, after only Los Angeles itself. A full rewrite adopted in 2017 created a dedicated preservation commission, a local register of cultural resources, and tools for historic districts and conservation overlays, work the Los Angeles Conservancy honored with a 2018 Preservation Award. Period property here comes with a real designation process and real records behind it.
The mission’s vocabulary, the buttress, the arcade, the tile and plaster, echoes through every revival neighborhood in the valley. The twenties chapter of that story continues four miles east in the town Walter Temple built. The full map of the valley’s communities lives in the communities library, and the city by city comparisons run in the valley cities cluster.
