The Lyzon Hat Shop Museum is the original shop of the acclaimed milliner, Walter King. Women of the Hamptons' Summer Colony frequented this business beginning in the 1920's through the 1960's. The exclusive collection of Mr. King's bespoke and uniquely designed Lyzon Hats are on display for your enjoyment. The Prosper King House, circa 1790, one of the oldest structures in the hamlet of Hampton Bays (formerly known as Good Ground) is open too.
