The Leonis Adobe Museum in Calabasas was named as the first Los Angeles historic monument on August 6, 1962. The Leonis Adobe was the home of Miguel Leonis, known as the King of Calabasas, who owned over 10,000 acres of land. The museum features his authentically furnished two-story Monterey-style adobe with original buildings, period livestock, gardens and a vineyard. The house was originally built in 1844, six years before Los Angeles was incorporated and California became a state.
Also on the property is the Plummer House, the oldest house in Hollywood and in 1935 was named California Historical Landmark No. 160. The house fell into disrepair and became dilapidated before the salvagable front portion of the house was moved to the Leonis Adobe site in 1983 and subsequently repaired, restored and refurbished. It now serves as the onsite Visitor Center and gift shop.
The Leonis Adobe, located at 23537 Calabasas Road in Calabasas (near the Sagebrush Cantina) is open Wednesday through Sunday from 1pm to 4pm (opens at 10am on Saturdays). Visit www.leonisadobemuseum.org or call 818.222.6511 for more information. Suggest donations are $4 for adults, $3 for seniors and $1 for children under age 12.
On a personal note, I've been to the Leonis Adobe and it is an amazingly large piece of property in the heart of old town Calabasas, paralleling, yet nearly invisible to, the 101 freeway. In addition to the historic buildings the site has a particularly impressive assortment of vintage wagons and farm equipment. There's also a beautiful, well manicured garden area and lots of farms animals to see and feed, including some longhorn bulls, sheep, goats, chickens and a horse. Bring quarters to buy food. Plus they have many activities for the kids year-round.
