"In 1903, a pair of Dutch-style windmills were built at the extreme western end of the park. These pumped water throughout the park. The north windmill has been restored to its original appearance and is adjacent to a flower garden, a gift of Queen Wilhelmina of the Netherlands. These are planted with tulip bulbs for winter display and other flowers in appropriate seasons. Murphy's Windmill in the south of the park is currently being restored." - http://en.wikipedia.org/wiki/Golden_Gate_Park
