The Jamestown Windmill is a 30-foot tall smock mill built in 1787. If you're passing through Jamestown, Rhode Island, and you've a passing interest in history, it's well worth a visit. The windmill is currently maintained in working order and once per year they put the fabric on the sails and let the wind take it. It's called a smock mill because of the shape of the building – usually octagonal – resembles an eighteenth century farmers smock. The bonnet on top rotates so the sails can catch the wind.
