Any fan of California history should have the Los Rios Historic District in San Juan Capistrano on their bucket list. It’s the oldest neighborhood in California, incidentally reaching its 250th anniversary this year (celebrated with free trolley tours) at the same time as the United States’ semiquincentennial.
Founded in 1776 by Junípero Serra, Mission San Juan Capistrano was the seventh of California’s Spanish missions, with the town and the historic Los Rios Street growing alongside it.
To this day, the street is still lined with original adobe homes from the late 1700s, three of which date back about 230 years, and the rest of which were built in the early 1900s by European immigrants.
One of the adobes, called the Rios Adobe, is the oldest continuously inhabited home in the western United States. It was constructed in 1794 by Santiago Rios and is still occupied by his descendants. You can see the home at 31781 Los Rios Street, but it is a private residence, so be sure to keep a respectful distance.
