Long Island Head Light
Long Island Head Light is an historic lighthouse on Long Island in Boston Harbor, Boston, Massachusetts. The current brick tower is the fourth lighthouse on the island. The light was first established in 1819, largely as a result of a study conducted by the Boston Marine Society, which had built the daybeacon on Nixes Mate 14 years earlier. It was a stone tower known as "Inner Harbor Light". It was the second of the four Boston lights—103 years after Boston Light, but ten years before the first daybeacon at the site of Deer Island Light, and before The Graves Light, built in 1905. In 1853, it was reported in the ''New England Farmer'', that Captain Charles A. Beck, was keeper of the Light for twenty-eight years. The stone tower fell into disrepair and was replaced by one of the earliest cast iron lighthouse structures, thirty-four feet tall (pictured below). In 1857, a fourth order Fresnel lens replaced the lamps and reflectors which had been in place. During the next tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Island (Massachusetts)
Long Island is located in Boston Harbor, Massachusetts. The island is part of the City of Boston, and of the Boston Harbor Islands National Recreation Area. The island is long and covers . Prior to October 2014, access to the island was via a road over a causeway from the Squantum peninsula of North Quincy to Moon Island, and from there, over a two-lane steel bridge – officially named the Long Island Viaduct – from Moon Island to Long Island. Access to the causeway leading to Moon Island and Long Island was controlled by police at a guardhouse at its southern end, and permission needed to be obtained in advance since it is a restricted area. In October 2014, all access to Long Island was cut off for the indefinite future by then Mayor of Boston, Marty Walsh, based on the warning of the Massachusetts Department of Transportation that the bridge was unsafe. All those living on Long Island and being serviced by recovery programs or who were guests in the homeles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Graves Light
The Graves Light is a lighthouse located on The Graves, the outermost island of the Boston Harbor Islands National Recreation Area, and offshore of downtown Boston, Massachusetts, USA. At , it is the tallest lighthouse in the approaches to the Port of Boston, and is an important navigation aid for traffic to and from the port. It was built at the same time that the North Channel into Boston Harbor was dredged to become the principal entrance for large vessels. The Graves are the outermost rocks near the outer end of the North Channel. It was added to the National Register of Historic Places as Graves Light Station on September 28, 1987, reference number 87002041. Construction and history The lighthouse was built in 1905, to a conical design using granite blocks on a granite foundation, and equipped with one of the few first-order Fresnel lens used. The lens assembly stands about 12 ft (4m) tall and is now at the Smithsonian Institution. The light was the setting for th ...

Lighthouses On The National Register Of Historic Places In Massachusetts
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Strong
Fort Strong is a former U.S. Army Coast Artillery fort that occupied the northern third of Long Island in Boston Harbor. The island had a training camp during the American Civil War, and a gun battery was built there in the 1870s. The fort was built in 1893-1906 during the Endicott period of expansion in U.S. coast defense, and was part of the Coast (later Harbor) Defenses of Boston. Formerly, it was also known as Long Island Military Reservation. Before World War I, a large station for handling submarine mines was added to the fort's defenses. Prior to World War I the fort was probably manned by over 1,000 soldiers. During World War II, two batteries of 3-inch guns (Basinger and Stevens) defended channel minefields, but the big guns and other 3-inch batteries (except for the AA guns) were decommissioned. Declared surplus in 1947, the fort served as a Nike missile site until 1961, and was redeveloped in 2005-2009 for a children's summer camp and later a homeless shelter. Howev ...

Newspapers
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th ...

Deer Island Light
Deer Island Light is a lighthouse in Boston Harbor, Boston, Massachusetts. The actual light is above Mean High Water. Its alternating white and red light is visible for . The light is at the end of a reef that extends about south from Deer Island. The location first had a stone beacon in 1832. The first light, a sparkplug type light, was lit in 1890. It cost about $50,000. It included a three-story dwelling, a veranda with boat davits, and a circular parapet. The water supply was a cistern in the base of the structure. A spiral staircase ran from the cellar to the top floor. It had a fixed white light, which was changed to flashing red every thirty seconds and then to the present alternating red and white flashes. The old light gradually deteriorated and was replaced in 1982 by a white fiberglass tower. The white tower raised complaints because it blended in with the background and was hard to see, so the Coast Guard moved it to Great Point Light, Nantucket, as a temporary ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The '' catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.

Boston Light
Boston Light is a lighthouse located on Little Brewster Island in outer Boston Harbor, Massachusetts. The first lighthouse to be built on the site dates back to 1716, and was the first lighthouse to be built in what is now the United States. The current lighthouse dates from 1783, is the second oldest working lighthouse in the United States (after Sandy Hook Lighthouse in New Jersey), and is the only lighthouse to still be actively staffed by the United States Coast Guard, being automated in 1998 though there is still a keeper acting as tour guide. The structure was designated a National Historic Landmark in 1964. History The first keeper of Boston Light was George Worthylake, who drowned, along with his wife and daughter, when returning to the island in 1718. During the American Revolution, the original lighthouse was held by British forces and was attacked and burnt on two occasions by American forces. As the British forces withdrew in 1776, they blew up the tower and comple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
