"Two Lighthouses In The Same Photo #2" by howardignatius on Flickr - This photograph shows both the Portland Head Light and the lessor known Ram Island Ledge Light. The Portland Light is a historic lighthouse in Cape Elizabeth, Maine - construction began in 1787. Materials used were rubble masonry and brick. Ram Island Ledge Light is a lighthouse in Casco Bay, Booth Harbor, Maine. It is no longer open to the public.
Ken Steiner, who owns the company and did the work himself, has been told by a local historian that his great-grandfather was a lighthouse keeper at Round Island. Description from lighthousefriends.com. I searched for this on bing.com/images
Blackwell Island Lighthouse, New York - This 50-foot-tall, gray gneiss, Gothic-style lighthouse was built in 1872. It is not an official Coast Guard lighthouse. The lighthouse’s purpose was to “effectually light” the nearby New York City Insane Asylum for boats navigating the treacherous Hell Gate waters. It was designed by architect James Renwick, Jr., whose other works include Smallpox Hospital and St. Patrick’s Cathedral. Inmate labor was probably used in the city-run project..
Duncansby Head #Lighthouse - The tidal streams flowing through the Pentland Firth earned it the title of hell's mouth in the days of sail, and it is still a place where unwary ships can become the plaything of the sea. As the waters of the wide Atlantic flow into the North sea and ebb in the opposite direction, they set in motion a welter of eddies, races and overfalls, and in the neighbourhood of the Pentland Skerries they run at a speed of ten knots. http://dennisharper.lnf.com/
