Built in 1885, Cypress Knoll is the oldest standing house in Mill Valley and was the home of Carmelita Garcia Boyle and Hugh Boyle. Carmelita's mother was the widow of John Reed, the original settler of Mill Valley, and Carmelita inherited 325 acres of John Reed's vast holdings from her mother. Carmelita and Hugh Boyle donated Boyle Park to the city, gave part of the property to their children, and sold the remainder. In 2004, the remains of three bodies dating back to the 1800's were discovered beneath the house.
