The Alviso Adobe, a 175-year-old farmhouse, is one of the oldest buildings in the area, made partly of original adobe bricks. In 2005, the Open Space Authority contributed $356,837 towards the City of Milpitas’ project to restore the building and expand the property and turn it into a city park, complete with a fruit orchard, picnic tables, restored outbuildings and interpretive signs highlighting various aspects of the farming and ranching done onsite over the years.
