Cape Ann Light StationCape Ann Light Station

Located on Thacher Island, this light station was established in 1771, and was the last founded in the colonial era. The two lighthouses were the first to mark a navigational hazard (Thacher Island); the current lighthouses were constructed in 1861, and are aligned on a north-south axis.[26] Photo: Tim Pierce, CC BY-SA 3.0, via Wikimedia Commons (https://commons.wikimedia.org/wiki/File:Thacher_Island_twin_lighthouses.jpg)
