Leonis Adobe, built in 1844, is one of the oldest surviving private residences in Los Angeles County and one of the oldest surviving buildings in the San Fernando Valley. Located in what is now Calabasas, California, the adobe was occupied by the wealthy rancher, Miguel Leonis, until his death in 1889. Following Leonis' death, the property was the subject of a legal dispute between his common law wife, 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 a Historic-Cultural Landmark (the first structure in Los Angeles receiving the designation) in 1962. Leonis Adobe is also known as one of the most haunted sites in Los Angeles County, and it was profiled in the British paranormal television series "Most Haunted" in 2005. The adobe was restored and is operated as a living museum. It was listed on the National Register of Historic Places in 1975.
