| 説明 | Taken today on a beautiful day to visit this lighthouse. There were lots of other visitors some of whom grace this photo. The lighthouse was commissioned in 1827 by President John Quincy Adams and built that year. Because of poor workmanship (salt water was used in the mortar mix), the lighthouse began to crumble and was replaced in 1835. The second contract for the construction stipulated that only fresh water be used. Keeper Isaac Dunham oversaw the construction and wrote in a letter to the US Lighthouse Establishment that the agreement was upheld and the work went well.The original light was an Argand-Lewis parabolic reflector, lit with candles and with a visibility of 2 miles (3.2 km). Augustin Fresnel invented a superior way of focusing light in the early 1850s and most lighthouses in the US were converted to the Fresnel Lens, with Pemaquid Point receiving a fourth order Fresnel in 1856. The lens is one of only six Fresnel lenses still in service in Maine. The keeper's house was built in 1857. By popular vote of Maine residents, the lighthouse was chosen to be featured on the Maine quarter, the 23rd in the 50 State Quarters Program issued by the U.S. Mint. Also depicted is a 3-masted schooner intended to resemble the Victory Chimes. Exposed bedrock descends from the lighthouse to the ocean creating a unique, scenic landscape. The geological history of these formations dates back hundreds of millions of years. These imposing structures have made this lighthouse with its setting one of the most photographed on the Maine coast.In addition to the image found on the state quarter, an image of Pemaquid Point lighthouse is featured as a possible background in Windows 7.[Wikipedia] |
