Delaware Breakwater Range Rear Light
The Delaware Breakwater Range Rear Light (also known as the Green Hill Light) was a lighthouse west of Lewes, Delaware. It was made obsolete by the shifting of Cape Henlopen and was disassembled and moved to Florida to become the Boca Grande Entrance Range Rear Light. History This light was erected in 1881 to form a range to guide ships around Cape Henlopen and into the relatively sheltered area behind it, which was also protected by the Delaware Breakwater. A typical skeletal tower of the period was constructed near Lewes on the shore of Delaware Bay and equipped with a third order Fresnel lens. A wooden keeper's dwelling was also constructed; this was supplemented with a second dwelling for an assistant in 1910, built of concrete. The original house was sold and eventually burned. Extensive ornamental gardens were planted on the grounds in 1901. The original front light was the Delaware Breakwater Range Front Light, a much older light situated at the west end of the breakwater ...

Lewes, Delaware
Lewes ( ) is an incorporated city on the Delaware Bay in eastern Sussex County, Delaware, United States. According to the 2010 census, the population is 2,747. Along with neighboring Rehoboth Beach, Lewes is one of the principal cities of Delaware's rapidly growing Cape Region. The city lies within the Salisbury, Maryland–Delaware Metropolitan Statistical Area. Lewes proudly claims to be "The First Town in The First State." History Lewes was the site of the first European settlement in Delaware, a whaling and trading post that Dutch settlers founded on June 3, 1631, and named Zwaanendael (Swan Valley).Munroe, John A.: ''Colonial Delaware: A History'': Millwood, New York: KTO Press; 1978; pp. 9–12. The colony had a short existence, as a local tribe of Lenape Native Americans wiped out the 32 settlers in 1632. The area remained rather neglected by the Dutch until, under the threat of annexation from the colony of Maryland, the city of Amsterdam made a grant of land at the Ho ...

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.

Cape Henlopen
Cape Henlopen is the southern cape of the Delaware Bay along the Atlantic coast of the United States. It lies in the state of Delaware, near the town of Lewes, where the Delaware Bay meets the Atlantic Ocean. Off the coast on the bay side are two lighthouses, called the Harbor of Refuge Light and the Delaware Breakwater East End Light. Early history Cape Henlopen, originally spelled Cape Hinlopen (after its namesake Thijmen Jacobsz Hinlopen who was a prominent Dutch trader), was New Netherland's southernmost border on the 37th parallel north. In 1620, Thijmen Jacobsz Hinlopen became the business partner of Cornelis Jacobsen Mey in the now washed out Cape Cornelius and the incorrectly spelled Cape May with the ships Blijde Boodschap (English: "Good News") and Bever both of which focused on exploration and trade with the Indians on the Delaware River (then Zuidt Rivier). The area between the 38th and 40th parallels (i.e., the Delaware Bay area) as well as the Delaware River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasparilla Island Lights
The Gasparilla Island Lights are on Gasparilla Island in Boca Grande, Florida. The Port Boca Grande Lighthouse is on the southern tip of Gasparilla Island (located in Gasparilla Island State Park), and marked the Boca Grande Pass entrance to Charlotte Harbor. Port Boca Grande Lighthouse Port Boca Grande Lighthouse was first lit on December 31, 1890. It is a two-story frame dwelling raised on iron screw-piles, with the lantern placed in a cupola at the peak of the roof. The keeper lived in the lighthouse. A similar house (without a lantern) built next to it was the assistant keeper's dwelling. The Port Boca Grande Lighthouse originally served ships transporting cattle from ports on Charlotte Harbor to Cuba. Phosphate ore from the Peace River area became an important cargo in the 1890s, and the construction of the Charlotte Harbor and Northern Railway to Port Boca Grande in 1909 resulted in increased traffic. Ship traffic to Port Boca Grande peaked at more than 30 ships a day d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware Breakwater
The Delaware Breakwater is a set of breakwaters east of Lewes, Delaware on Cape Henlopen that form Lewes Harbor. They were listed on the National Register of Historic Places on December 12, 1976. The original and breakwaters were built in 1828. The breakwaters are now included in the National Harbor of Refuge and Delaware Breakwater Harbor Historic District. The stone for the breakwater were quarried from what later became Bellevue Lake in New Castle County. The breakwaters were the first structure of their kind to be built in the Americas.

Delaware Bay
Delaware Bay is the estuary outlet of the Delaware River on the northeast seaboard of the United States. It is approximately in area, the bay's freshwater mixes for many miles with the saltwater of the Atlantic Ocean. The bay is bordered inland by the states of Delaware and New Jersey, and the Delaware Capes, Cape Henlopen and Cape May, on the Atlantic. Delaware Bay is bordered by six counties: Sussex, Kent, and New Castle in Delaware, along with Cape May, Cumberland, and Salem in New Jersey. The Cape May–Lewes Ferry crosses Delaware Bay from Cape May, New Jersey, to Lewes, Delaware. The bay's ports are managed by the Delaware River and Bay Authority. The shores of the bay are largely composed of salt marshes and mudflats, with only small communities inhabiting the shore of the lower bay. Several of the rivers hold protected status for their salt marsh wetlands bordering the bay, which serves as a breeding ground for many aquatic species, including horseshoe crabs. The bay ...

Delaware Breakwater East End Light
The Delaware Breakwater East End Light is a lighthouse located on the inner Delaware Breakwater in the Delaware Bay, just off the coast of Cape Henlopen and the town of Lewes, Delaware. Construction and early use In 1884 a light was commissioned for the east end of the Delaware Breakwater. The light was built to replace the Cape Henlopen Beacon, which was rapidly deteriorating at the time and was taken out of service later that same year. Construction began in 1885 and a temporary light on a wooden frame was placed near the building site during the process. The foundation of the tower was embedded into the breakwater. The iron structure, which was listed at tall as of 1914, was completed on October 2, 1885. The tower was fitted with a fourth-order Fresnel lens—which is still in the lighthouse to this day—and also included one red sector in order to warn vessels approaching the nearby Hen and Chickens Shoal. A fog signal was installed about a month later. During the follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasparilla Island
Gasparilla Island is a barrier island in southwest Florida, United States, straddling the border of Charlotte and Lee counties. Its largest town is Boca Grande, and it is the location of the Gasparilla Island State Park. The island has been an important part of Florida folklore due to its connection to the pirate Gasparilla (José Gaspar), and has been a significant tourist]destination since the early 20th century. Location Gasparilla spans the border of Charlotte and Lee counties in Southwest Florida. To the west is the Gulf of Mexico, while to the east and south is Charlotte Harbor. To the north is Gasparilla Pass, separating Gasparilla from Little Gasparilla Island and the mainland. History Gasparilla was sparsely inhabited until the late 19th century, with the only permanent residents being local fishing families.Stephens, p. 9. In 1848 the United States military established an outpost at Boca Grande. In 1897 Albert W. Gilchrist, future governor of Florida, purchased l ...

Lighthouses In Sussex County, Delaware
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 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
