Jordan Point Light
The Jordan Point Light was a lighthouse located on Jordan Point on the James River in Prince George County, Virginia, near the south end of the present Benjamin Harrison Memorial Bridge. History The history of this station is unclear, but some sources indicate that a light station was first established on Jordan Point in 1855. This consisted of a keeper's house with a masthead light on the roof. This arrangement was replaced circa 1875 (possibly as early as 1870) by a separate pyramidal wooden tower that housed a sixth order Fresnel lens and a fog bell. A new keeper's house was constructed in 1888. In 1927 the station was deactivated and the wooden tower was later demolished. In 1941 a new steel skeleton tower was erected on the site of the old tower; this skeleton tower is still in service as the rear light of the Jordan Point Range, Light List #2-12420. Although the wooden tower is long gone the keeper's house built in 1888 still stands. It was extensively renovated in 200 ...

The river length extends to if one includes the Jackson River, the longer of its two source tributaries. It is the longest river in Virginia. Jamestown and Williamsburg, Virginia's first colonial capitals, and Richmond, Virginia's current capital, lie on the James River. History The Native Americans who populated the area east of the Fall Line in the late 16th and early 17th centuries called the James River the Powhatan River, named for the chief of the Powhatan Confederacy which extended over most of the Tidewater region of Virginia. The Jamestown colonists who arrived in 1607 named it "James" after King James I of England (), as they constructed the first permanent English settlement in the Americas at Jamestown along th ...

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] |
Jordan Point, Virginia
Jordan Point (or Jordan's Point) is a small unincorporated community on the south bank of the James River in the northern portion of Prince George County, Virginia, United States. It is about 20 miles from Richmond and 30 miles upstream from Jamestown on the James River. It was the location of extensive archeological research between 1987 and 1993. This research provided substantial information about human existence in the area from the prehistoric to the late colonial eras. In particular, the research extensively studied the Jordan's Journey settlement that existed between 1620-1640 during early years of the Virginia colony. Early history Native American Culture Though the area around Jordan Point had been occupied by native Americans for millennia, archeologists have found evidence of settled agricultural settlements that date from the late Woodland and English-Native American Contact periods, dating between 1150 to the early 1600s. The archaeological findings suggest that d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Benjamin Harrison Memorial Bridge
The Benjamin Harrison Memorial Bridge is a vertical-lift bridge that spans the James River between Jordan's Point in Prince George County and Charles City County near Hopewell, Virginia. The bridge carries vehicle traffic of State Route 106 and State Route 156, and is owned by the Virginia Department of Transportation (VDOT). It is named after Benjamin Harrison V, a signer of the Declaration of Independence and a Governor of Virginia, who lived nearby at Berkeley Plantation. Originally completed in 1966, it was substantially rebuilt following a February 24, 1977 collision by a ship. Repairs took 20 months to complete. The cost of repairs and operations for an innovative passenger shuttle service contracted by the state were $9.7 million. The costs were recovered from the insurer for the shipping company following a lawsuit in U.S. District Court. Working in conjunction with the College of William and Mary in Williamsburg, the Benjamin Harrison Bridge and its VDOT staff host a ...

United States Lighthouse Society
The United States Lighthouse Society is a non-profit organization dedicated to aiding in the restoration of American lighthouses and educating the public about their history. With four chapters, and more than a dozen affiliates, it is one of the largest and oldest lighthouse organizations in the world. History Founded in 1984 by Wayne Wheeler and initially headquartered in San Francisco, California, one of the United States Lighthouse Society's first major projects was the purchase of the lightship LV605 in 1986 from a private individual. The organization subsequently invested $400,000 and more than 40,000 volunteer hours in the preservation and restoration of the vessel. In 2003 the society received the California Governor's Historic Preservation Award for its work on the ship. The society relocated from California to Hansville, Washington in 2008, siting its headquarters at the historic Point No Point Lighthouse, which it rented from Kitsap County (the county, in turn, lease ...

Houses Completed In 1888
A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems.Schoenauer, Norbert (2000). ''6,000 Years of Housing'' (rev. ed.) (New York: W.W. Norton & Company). Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
