Sabin Point Light
The Sabin Point Light was a lighthouse in the Providence River. It was removed as part of a channel-widening project in 1968. History This light was constructed in 1872 to mark a bend in the shipping channel southwest of Sabin Point. The Second Empire style house was constructed according to a plan by Albert R. Dow, the winning design in a contest sponsored by the Lighthouse Service. Nearly identical lights were constructed at Colchester Reef, Pomham Rocks, Esopus Meadows Light and Rose Island. Initially the keeper also had responsibility for the beacon which was replaced in 1876 by the Bullock's Point Light. The light weathered the hurricane of 1938 fairly well, albeit with serious flood damage to the first floor. The keeper's wife, Annie Whitford, was washed away three times, but managed not only to survive but to keep the light going through the storm. On a less perilous note, two of her daughters were married at the light, the second to the son of the keeper of the Warwi ...

Lighthouses In Rhode Island
This is a list of all lighthouses in the U.S. state of Rhode Island as identified by the United States Coast Guard. There are fifteen active lights in the state as well as two skeleton towers erected to replace earlier staffed lighthouses. The first lighthouse in the state was erected in 1749 and the last in 1962 (ignoring automated towers erected later); the oldest surviving structure is the much-modified Poplar Point Light, although the tower now standing at Prudence Island Light was first erected at Goat Island in 1824. The tallest extant tower is that at Beavertail Light, though the focal plane of the Block Island Southeast Light is much higher on account of the bluffs upon which it sits. If not otherwise noted, focal height and coordinates are taken from the United States Coast Guard ''Light List'', while location and dates of activation, automation, and deactivation are taken from the United States Coast Guard historical information site for lighthouses.

Providence River
The Providence River is a tidal river in the U.S. state of Rhode Island. It flows approximately 8 miles (13 km). There are no dams along the river's length, although the Fox Point Hurricane Barrier is located south of downtown to protect the city of Providence from damaging tidal floods. The southern part of the river has been dredged at a cost of $65 million in federal and state funds to benefit nearby marinas and commercial shipping interests. The Dutch called the Providence River the ''Nassau River''. It was the northeastern limit of Dutch claims in the colonial era, owing to Adriaen Block's exploration of Narragansett Bay, from 1614 until the Hartford Treaty of 1650. It can, therefore, be regarded as the original boundary between the English New England colonies and the Dutch colony of New Netherland. Course The river is formed by the confluence of the Woonasquatucket and Moshassuck rivers in downtown Providence. One half mile downstream, it is joined from the east ...

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. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Empire (architecture)
Second Empire style, also known as the Napoleon III style, is a highly eclectic style of architecture and decorative arts, which uses elements of many different historical styles, and also made innovative use of modern materials, such as iron frameworks and glass skylights. It flourished during the reign of Emperor Napoleon III in France (1852–1871) and had an important influence on architecture and decoration in the rest of Europe and North America. Major examples of the style include the Opéra Garnier (1862–1871) in Paris by Charles Garnier, the Bibliothèque nationale de France, the Church of Saint Augustine (1860–1871), and the Philadelphia City Hall (1871–1901). The architectural style was closely connected with Haussmann's renovation of Paris carried out during the Second Empire; the new buildings, such as the Opéra, were intended as the focal points of the new boulevards.

Colchester Reef Light
The Colchester Reef Light in Vermont was a lighthouse off Colchester Point (northwest of Burlington, Vermont) in Lake Champlain. It was moved to the Shelburne Museum in Shelburne, Vermont, in 1956. In 1869 the United States Lighthouse Service commissioned the building of the Colchester Reef Lighthouse on Lake Champlain to protect ships from the "Middle Bunch Reef", comprising the Colchester Reef, the Colchester Shoals, and the Hogback Reef.Shelburne Museum. 1993. ''Shelburne Museum: A Guide to the Collections''. Shelburne: Shelburne Museum, Inc. Architecture This lighthouse was one of a group of New England lighthouses built to the same plan. Nearly identical lighthouses were constructed at Esopus Meadows Light in New York and Sabin Point, Pomham Rocks, and Rose Island, all three located in Rhode Island waters.

Pomham Rocks Light
Pomham Rocks Light (also known as "Pomham Lighthouse") is a historic lighthouse in the Providence River about off the shoreline of the Riverside neighborhood of the city of East Providence, Rhode Island. It is the northernmost lighthouse in Narragansett Bay. History The light was established in 1871. The light was one of a group of New England lighthouses built to the same plan after an award-winning design by Vermont architect Albert Dow. Nearly identical lights were constructed at Sabin Point, Rose Island, Esopus Meadows Light and Colchester Reef. The lighthouse was decommissioned in 1974, and its antique fourth-order fresnel lens donated to the Custom House Maritime Museum in Massachusetts. The lighthouse was sold to a private family in 1974. In 1980 it was acquired by ExxonMobil, which operates a fuel terminal nearby. In 2010, ExxonMobil donated the building and island to the American Lighthouse Foundation, the parent organization of the Friends of Pomham Rocks Lighthouse. ...

Rose Island Light
The Rose Island Light, built in 1870, is on Rose Island in Narragansett Bay in Newport, Rhode Island in the United States. It is preserved, maintained and operated by The Rose Island Lighthouse Foundation. One of a group of New England lighthouses built to an award-winning design by Vermont architect Albert Dow, Rose Island Light has sisters at Sabin Point, Pomham Rocks, Esopus Meadows Light and Colchester Reef. The lighthouse stands atop a bastion of Fort Hamilton, which was built in 1798-1800. The building was abandoned as a functioning lighthouse in 1970, when the Newport Bridge was constructed nearby. In 1984, the Rose Island Lighthouse Foundation was founded to restore the dilapidated light on behalf of the City of Newport, which had received it for free from the United States government.

Bullock's Point Light
The Bullock's Point Light was a lighthouse in the Providence River. It was irreparably damaged by the hurricane of 1938 and was replaced the following year by an automated light on a steel tower. History A large shoal extends out into the Providence River from Bullock's Point, and in 1860 the Lighthouse Board set a daymark at the southwest tip of the shoal. Complaints about the adequacy of this grew as shipping increased, and in 1872 built a small pier at the site and set a portable beacon on it, maintained by the keepers of the Sabin Point Light. This too was deemed inadequate, and starting in 1875 the pier was enlarged, and a unique frame house was perched upon it, with the lantern projecting from the center of the roof. Difficulties in construction due to bad weather delayed lighting of the new beacon until 1876. Over the years decking was added at the base of the house. Although the Hurricane of 1938 The 1938 New England Hurricane (also referred to as the Great New England ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dolphin (structure)
A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids. Structure Dolphins typically consist of a number of piles driven into the seabed or riverbed, and connected above the water level to provide a platform or fixing point. The piles can be untreated or pressure treated timber piles, or steel or reinforced concrete piles. Smaller dolphins can have the piles drawn together with wire rope, but larger dolphins are typically fixed using a reinforced concrete capping or a structural steel frame. Access to a dolphin may be via a pedestrian bridge, particularly in the case of mooring dolphins, but is often by boat. Use As mooring point Dolphins are usually installed to provide a fixed structure when it would be impractical to extend the shore to provide a dry- ...

Day Beacon
A day beacon (sometimes "daybeacon") is an unlighted nautical sea mark. A signboard identifying it is called a day mark. Day beacons typically mark channels whose key points are marked by lighted buoys. They may also mark smaller navigable routes in their entirety. They are the most common navigation aid in shallow water, as they are relatively inexpensive to install and maintain. Navigation around them is similar to that around other navigation aids. Identification Lateral marking For historical reasons, there are two systems for lateral day beacons. When proceeding from open water towards harbor, marks with cylindrical topmarks or square dayboards are kept to port in both regions, but colors and numbers are reversed. When lateral beacons are paired, vessels should pass between the pairing. However, beacons are also frequently placed individually. Generally, single lateral beacons are at the inside corner of a turn. Interior or exterior placement can be determined based up ...
