The Muckenthaler House, also known as the Muckenthaler Cultural Center, is a large Spanish Colonial Revival-style mansion in Fullerton, California, erected in 1924 and has since been restored. A primary goal of the Muckenthaler Cultural Center is to preserve the heritage of the Muckenthaler estate while also providing engaging educational opportunities through exhibitions, live performances, and other events.

The Muckenthaler Mansion, built atop a hill in Fullerton in 1924 for $35,000, was commissioned by Walter and Adella Muckenthaler originally cost $35,000 to construct. The city received the 18-room palace on 8.5 acres in 1965 as a gift from Harold Muckenthaler, who intended to see his childhood home used as a cultural center for the community. The Muckenthaler House / Muckenthaler Cultural Center was officially listed on the National Register of Historic Places in 1999, and it has been there ever since.

In 1965 the property was converted into a cultural center. The Muckenthaler gave their home and grounds to the City of Fullerton. The Cultural Groups Foundation of Northern Orange County was established in 1966 as a non-profit organization. They collaborated with the city in the operation of the center. The center has been in operation since 1966. The Center Circle Guild was established in 1967 to provide extra support and volunteers for the center’s various programs. They also maintained the gift shop, funded the annual Florence Arnold Young Artists Festival, the Holiday Home Tour, and provided financial assistance for exhibition-related and education initiatives, among other things.

The Muckenthaler residence was listed on the National Register of Historic Places in 1980, making it a historic property. In the years 1981 to 1984, the facility underwent a comprehensive refurbishment. The first Master Plan, for the Muckenthaler, was created in 1984, and it outlined the future of the property. The construction of a new outdoor amphitheater took place between 1990 and 1993. The Muckenthaler Cultural Center Foundation was established in 1990 after the Foundation changed its name.

The Muckenthaler changed ownership in 1994, with the foundation taking over management of the institution and its grounds. The Jane Deming Endowment was established to promote, preserve, and aid the Foundation, in its objective of educating and empowering women.
