Shadelands Ranch, Colonial Revival farm in Walnut Creek, United States.

Shadelands Ranch is a two-story Colonial Revival farmhouse with curved glass bay windows, white columns and a hand-crafted shingle roof. The house was built in 1903, not 1902, and its period rooms display much of the Pennimans' original furniture.

Hiram Penniman founded the ranch in 1856 as one of the first major fruit and nut farming operations in California's Ygnacio Valley. The property grew to become an important agricultural center for the developing region.

The Walnut Creek Historical Society preserves this place as a museum where visitors can see how the family lived through original furnishings and household items. Educational programs help visitors understand the daily life and customs of people who worked the land in this valley during the early 1900s.

The ranch house stands at 2660 Ygnacio Valley Road, and the Walnut Creek Historical Society has run it as a museum since 1972. Much of the Pennimans' original furniture remains in the rooms. The remaining grounds cover about 1.5 acres, so a visit takes little time.

The property changed hands multiple times through the Penniman family line over several decades before a religious foundation donated it to the city in 1970. This transfer ensured the historic house would be preserved for public education rather than lost to development.
