Yesterday I went on the SF City Guides Golden Gate Park: West End tour. Among other points of interest the tour stops at the park’s two windmills — the Dutch Windmill to at the northwestern corner of the park, and the Murphy Windmill a block or two south.
Most of the time the windmills are completely still — not due to a lack of wind, but the potential for too much of it. If they were allowed to spin freely they could break apart and become a safety hazard, so they’re typically latched in place.
For whatever reason the Murphy Windmill was spinning yesterday morning, as you can see in the video above. I’d never seen either windmill spinning in person before; the motion makes the windmill look even larger and more majestic than when it’s sitting stationary.
Why does Golden Gate Park have windmills? They were built in the late 19th and early 20th century as the park’s irrigation system, pumping water out of wells up into lakes in the park. Unfortunately for the windmills, electric pumps became available shortly after they were built. No longer needed, the windmills began to decay and the metal in the internal mechanisms was salvaged for scrap.
But San Francisco’s love for antiques meant there was interest in preserving the windmills, similar to how the cable cars avoided destruction. The Dutch Windmill was restored in 1981 and the Murphy Windmill much more recently in 2012. For more details on the history of the windmills and the preservation efforts, read this 2007 paper from University of Vermont student Sarah LeVaun Graulty, which also includes historic photos and illustrations.
My favorite bit of trivia I learned from the City Guides tour is also mentioned in the paper. Golden Gate Park’s windmills are Dutch-style, but are far larger than those in the Netherlands. So what do Dutch windmill enthusiasts call this pair of unique windmills? What else could they be called — the “San Francisco Giants.”
