"Don't miss this treat to explore the Golden Gate Park windmills! The windmills were built in 1902 and 1905 to pump water for the irrigation of the Park. But electric pumps were eventually installed for efficiency, the windmills stopped their twirling and the salty sea wind got the better of these beauties. A recent campaign to save the windmills raised money for their resurrection. Our tour guide, Mark de Jong of Bloemendal Construction is the San Franciscan-Dutchman charged with this prodigious restoration project."
