Old Mill

San Marino, Los Angeles County · California

Mission San Gabriel needed flour, so around 1816 Father José María de Zalvidea had Tongva labourers raise this two-storey mill of fired brick and adobe, water off the canyons turning tufa stones on the upper floor. The design splashed damp into the meal, and a better mill went up nearer the mission in 1823. Colonel Kewen lived in the shell for twenty years, and Henry Huntington bought it in 1903 for a golf clubhouse. It is the oldest commercial building in Southern California.

What the plaque says

Originally located in the upper story of El Molino Viejo, these volcanic tufa millstones ground grain for the Indian community of Mission San Gabriel. The stones were turned by water flowing from nearby canyons. When the mill fell into disuse, the stones disappeared. A century later they were found on the Huntington Library grounds by General George S. Patton, who, as a young boy had seen them used as blocks for mounting horses.
