Leonis Adobe

The Leonis Adobe is a historic adobe located in what is now Calabasas, California. One of the oldest surviving private residences in Los Angeles County and one of the oldest surviving buildings in the San Fernando Valley, it was built in 1844 and was occupied by the wealthy rancher Miguel Leonis (October 20, 1824 – September 20, 1889) until his death. Afterward, the property was the subject of a legal dispute between his common-law wife, Espiritu Chijulla (1836 – May 10, 1906); heirs; and a daughter born out of wedlock. The dispute lasted more than 15 years in the courts.

In 1961, the adobe had fallen victim to vandalism, and its owner applied for a permit to raze the structure and erect a supermarket in its place. Preservationists succeeded in having the adobe declared Los Angeles Historic-Cultural Monument #1 in 1962, saving it from the wrecking ball at the last minute. It was listed on the National Register of Historic Places in 1975.

The adobe was restored and is operated as a living museum.
