Cabra Island Lighthouse
The Cabra Island Lighthouse is a historic lighthouse built on Cabra Island, the north-westernmost of the Lubang group of islands in Occidental Mindoro, Philippines. International vessels entering the Philippines from South China Sea were welcomed by the Cabra Light and directed either towards Manila Bay or the center of the archipelago through Verde Island Passage, one of busiest sea routes of the Philippines. History The lighthouse of Cabra was the first completed during Spain's revitalized program of lighthouse construction in the Philippines. Construction was started on May 3, 1885, and it was first lit on March 1, 1889.Noche, Manuel M., "Lonely Sentinels of the Sea, The Spanish Lighthouses in the Philippines", p.55. U.S.T. Publishing House, 2005. It was also the first of the five first-order lighthouses built by the Spaniards in the latter part of their colonization of the archipelago.

History Of The Philippines (1521–1898)
Earliest hominin activity in the Philippine archipelago is dated back to at least 709,000 years ago. ''Homo luzonensis'', a species of archaic humans, was present on the island of Luzon at least 67,000 years ago. The earliest known anatomically modern human was from Tabon Caves in Palawan dating about 47,000 years. Negrito groups were the first inhabitants to settle in the prehistoric Philippines. By around 3000 BC, seafaring Austronesians, who form the majority of the current population, migrated southward from Taiwan. Scholars generally believe that these ethnic and social groups eventually developed into various settlements or polities with varying degrees of economic specialization, social stratification, and political organization. Some of these settlements (mostly those located on major river deltas) achieved such a scale of social complexity that some scholars believe they should be considered early states. This includes the predecessors of modern-day population centers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses In The Philippines
With the Philippine Archipelago comprising over 7,100 islands packed in an area of , the country has the fifth-longest coastline in the world. The Philippine coast has a total length of and is very irregular, with numerous bays, gulfs, and islets. Eleven of the largest islands of the archipelago are the major islands and main centers of population, with ten of its most populous cities located along the coast. Approximately 1,000 of the smaller islands are also populated. With more than of coasting routes and tortuous channels regularly navigated by vessels trading among some 300 separate ports, navigation aids like lighthouses help mariners against misnavigation and guide them to safety and out of danger from grounding on its treacherous reef and shoals. Large international ships rely on lighthouses to guide them safely out from the open sea and into Philippine waters. Once within Philippine waters, lighthouses help them maneuver through its narrow straits and channels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses Completed In 1889
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] |

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.

Philippine Coast Guard
The Philippine Coast Guard (PCG) ( fil, Tanod Baybayin ng Pilipinas) is recognized as the third armed uniformed service of the country attached to the Philippines' Department of Transportation, tasked primarily with enforcing laws within Philippine waters, conducting maritime security operations, safeguarding life and property at sea, and protecting marine environment and resources; similar to coast guard units around the world. In case of a declaration of war, the Coast Guard shall also serve as an attached service of the Department of National Defense. It currently maintains a presence throughout the archipelago, with thirteen Coast Guard Districts, fifty-four CG Stations and over one hundred ninety Coast Guard Sub-Stations, from Basco, Batanes to Bongao, Tawi-Tawi. History Colonial era history The Philippine Coast Guard is the oldest and only humanitarian armed service in the Philippines. Its beginnings could be traced back to the early 20th century when coast guardin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Verde Island Passage
The Verde Island Passage is a strait that separates the islands of Luzon and Mindoro in the Philippines, connecting the South China Sea with the Tayabas Bay and the Sibuyan Sea beyond. Traditionally, the sea lane has been one of the busiest in the Philippines because it acts as a corridor from the Port of Manila to the Visayas and Mindanao in the south. A network of ferry routes cross the passage and connect the surrounding provinces of Batangas, Marinduque, Occidental Mindoro, Oriental Mindoro and Romblon. The 1.14 million hectare passage is extremely rich in marine biodiversity and has been called "Center of the Center of Marine Shorefish Biodiversity" with various conservation groups pushing for its nomination as a UNESCO World Heritage Site. Diving Verde Island, located right in the center of the strait, is a popular diving location in the Philippines due to its clear waters and renowned biodiverse marine life. Daily trips for scuba divers are made from Puerto Galera, Ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manila Bay
Manila Bay ( fil, Look ng Maynila) is a natural harbor that serves the Port of Manila (on Luzon), in the Philippines. Strategically located around the capital city of the Philippines, Manila Bay facilitated commerce and trade between the Philippines and its neighboring countries,Jacinto, G.S., Azanza, R.V., Velasquez, I.B. and Siringan, F.P.(2006)."Manila Bay:Environmental Challenges and Opportunities" in Wolanski, E.(ed.) The Environment in Asia Pacific Harbours. Springer: Dordrecht, Netherlands. p309-328. becoming the gateway for socio-economic development even prior to Spanish occupation. With an area of , and a coastline of , Manila Bay is situated in the western part of Luzon and is bounded by Cavite and Metro Manila on the east, Bulacan and Pampanga on the north, and Bataan on the west and northwest.Jacinto, G.S., Velasquez, I.B., San Diego-McGlone, M.L., Villanoy, C.L. and Siringan, F.B.(2006)."Biophysical Environment of Manila Bay - Then and Now", in Wolanski, E.(ed.)Th ...
