Located at the outer end of Boston Harbor, this islands history dates to 1690 when an English fleet used it as a staging point for an attack on Canada. In 1778 the French occupied the island, and in 1833, American Fort Warren was established here. In 1861, it held Confederate prisoners of war. The fort was decommissioned in 1928, but reactivated briefly during WWII. It has been vacant since. The site
