Ingleside Sundial

This giant time-telling apparatus has a circular diameter of 34 feet while its triangular piece is 78 feet long at its hypotenuse. Needless to say the shadow it casts over 148-acre park is long but it has shored up property prices even in this already expensive San Francisco neighborhood. Built in 1913, this timepiece of ancient technology is still as pristine as it was at its first unveiling.
