Punta Tuna Light
Punta Tuna Light is a historic lighthouse located in the southeast of the town of Maunabo, Puerto Rico on a narrow promontory at the southeasternmost point of the island. It was first lit in 1892 and automated in 1989. The light was a third-order lighthouse that served as the primary light connecting the island's southern and eastern lights system. The design was drawn and laid out by Joaquin Gisbert in 1890. The lighthouse construction was initially overseen by Adrian Duffaut. It was built from March 13, 1891, to September 29, 1893. Final construction was taken over by the Spanish Body of Engineers according to annotations of the historian Carlos Moral. It was originally named Faro de Mala Pascua after the cape to the west. Later, it was moved and renamed after the Point of the construction site so the light could perform a double duty warning ships off the Sargent reef. On August 8, 1899, the lighthouse suffered damage from Hurricane San Ciriaco; the town suffered heavy damage. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maunabo, Puerto Rico
Maunabo () is a town and municipality of Puerto Rico located in the Maunabo Valley on the southeastern coast, northeast of Patillas and south of Yabucoa. Maunabo is spread over eight barrios and Maunabo Pueblo (the downtown area and the administrative center of the city). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area. The current mayor of the town is Jorge L. Márquez Pérez and the population in 2020 was 10,589. History Maunabo was founded in 1799. Maunabo derives its name from a Taino name ''Manatuabón'' for the Maunabo River. Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became a territory of the United States. In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Maunabo was 6,221. Maunabo is known for its advances in media. Being almost "disconnected" from the rest of the island by its high mountains, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Neoclassical Architecture
Neoclassical architecture is an architectural style produced by the Neoclassical movement that began in the mid-18th century in Italy and France. It became one of the most prominent architectural styles in the Western world. The prevailing styles of architecture in most of Europe for the previous two centuries, Renaissance architecture and Baroque architecture, already represented partial revivals of the Classical architecture of ancient Rome and (much less) ancient Greek architecture, but the Neoclassical movement aimed to strip away the excesses of Late Baroque and return to a purer and more authentic classical style, adapted to modern purposes. The development of archaeology and published accurate records of surviving classical buildings was crucial in the emergence of Neoclassical architecture. In many countries, there was an initial wave essentially drawing on Roman architecture, followed, from about the start of the 19th century, by a second wave of Greek Revival architec ...

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] |
General Services Administration
The General Services Administration (GSA) is an independent agency of the United States government established in 1949 to help manage and support the basic functioning of federal agencies. GSA supplies products and communications for U.S. government offices, provides transportation and office space to federal employees, and develops government-wide cost-minimizing policies and other management tasks. GSA employs about 12,000 federal workers. It has an annual operating budget of roughly $33 billion and oversees $66 billion of procurement annually. It contributes to the management of about $500 billion in U.S. federal property, divided chiefly among 8,700 owned and leased buildings and a 215,000 vehicle motor pool. Among the real estate assets it manages are the Ronald Reagan Building and International Trade Center in Washington, D.C., which is the largest U.S. federal building after the Pentagon.

List Of Lighthouses In Puerto Rico
The lighthouses system of Puerto Rico consists of lighthouses that were built mostly during the last twenty years of the nineteenth century. These served as guides to important marine routes. In 1869 the Spanish government approved the first plan for Puerto Rico in order to serve the ships that sail through its waters. The lighthouses are located in prominent and isolated areas with good visibility towards the sea. The classification system of the lighthouses of Puerto Rico was based on the characteristics of the lens, and the structure. The lights of the first and second order have a wider light to warn ships of the proximity to land, followed by the minor lights, whose scope was limited to smaller harbors and bays and to connect the primary lights in the system. In 1898, the United States acquired the lighthouses of Puerto Rico as a result of the Spanish–American War. In 1900, the United States Lighthouse Board acquired responsibility for the aids to navigation. The lights a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic American Engineering Record In Puerto Rico
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
