My page on
Windmills in California details the two windmills in Golden Gate Park. I'm not sure
of the current state of the southernmost windmill, the Murphy Windmill, which was dismantled for reconstruction a few years ago.
(The timeline page at the
Campaign to save the Golden Gate Park Windmills
suggests that work should have started by now to rebuild this).
I have been able to find a few photos of the windmills via the various mapping and aerial photo services available on the web, though
these images are undated. All images currently seem to show the Murphy Windmill dismantled with just the base remaining.
