It is the last farm site in the city of Santa Clara and is named for the two families who owned and lived on the property for 125 years. The museum consists of the house, a classic California barn, summer kitchen, tank house and landscaped gardens. The house was built in 1865 in the Italianate style, balanced and symmetrical. In the 1890’s it was extensively enlarged and remodeled, changing the symmetry of the original design. It is fully furnished, most of the furniture and contents having belonged to the Lass family.
