San Francisco’s Murphy Windmill will star in a celebration of both Golden Gate Park windmills and all things Dutch Saturday.

Though the Murphy Windmill’s restoration is not quite complete, it is now able to turn, along with its sister to the north, the Dutch Windmill.

Saturday’s festivities coincide with Queen’s Day, a Dutch national celebration of the country’s queen that will be held in Golden Gate Park for the first time. The Queen’s Day events in Golden Gate Park start at 11 a.m. at the Murphy Windmill on Martin Luther King, Jr. Drive.

Both windmills were essential equipment for the creation of Golden Gate Park, drawing water from the ground to supply trees and other plantings where once there had been little vegetation and an abundance of blowing sand. They also have served as the location of publicity stunts such as a 1921 event in which a woman rode the sails of the Dutch Windmill for 25 rotations.
