Windmill in Golden Gate Park
Since Golden Gate Park was built on sand dunes, it required a great deal of soil enrichment and irrigation to turn it into the lovely green space it is today.
The irrigation is all underground, and used to be distributed by pumps powered by windmills. This is one of the few windmills still standing.
