• 1807: Island purchased from David Fayerweather by the US Government. • 1823: The present lighthouse was built, with four-foot-thick rubble walls faced with brownstone ashlar, to replace an earlier wooden structure that had been washed away in a hurricane. A keeper's house was constructed at the same time. • 1837–38: A granite
