Although planned for construction in the 18th century, work did not start until 1837 and it was completed in 1842. History Following the 1755 Lisbon earthquake, 1755 earthquake that affected much of Portugal the Sebastião José de Carvalho e Melo, 1st Marquis of Pombal, Marquis of Pombal, who was placed in charge of reconstruction, created an organized Lighthouse Service in 1758 and ordered six lighthouses to be built. The Berlenga lighthouse was intended to be one of these but, unlike the other five, it was not built. Only in December 1836 did the Portuguese Ministry of Finance (Portugal), Ministry of Finance commiss ... [...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.

Lighthouses In Portugal
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] |

Lighthouse Of Cabo Carvoeiro
The Lighthouse of Cabo Carvoeiro ( pt, Farol do Cabo Carvoeiro) is an active lighthouse in the civil parish of Peniche, municipality of the same name, in the Portuguese district of Leiria. History On 1 February 1758, the lighthouse was ordered constructed by regal charter. Cabo Carvoeiro is a prominent cape along the southern Portuguese coast, with a coastal beacon operating for four centuries from the promontory, first from the chapel of Nossa Senhora de Vitória (before it was demolished). The first purpose-built structure was a tall lighthouse that started to operate in 1790, but identified as inadequate by an 1881 commission. In 1865, the lighthouse was described in this form: :''...it is found at an elevation of 55.52 metres. The light is white and fixed, produced by sixteen Argand with parabolic reflectors. The range exceeds about 9 miles. The lantern where this mechanism was installed has a 8.24 metre height and eight faces with a width of 1.67 metre...The building where ...

Foghorn
A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards such as rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rock outcrops, shoals, headlands, or other dangers to shipping. Description All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, such as the Daboll trumpet, used vibrating plates or metal reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a siren. Semi-automatic operation of foghorns was achieved by using a clockwork mechanism (or "coder") to sequentially open the valves admitting air to the horns; each horn was given its own timing characteristics to help ...

Santa Marta Lighthouse
The Santa Marta Lighthouse is situated to the south of the centre of Cascais, Lisbon District, Portugal, on the estuary of the River Tagus, providing a light for the Cascais Bay and for the town's new marina. It is a quadrangular masonry tower covered with white tiles, with blue horizontal stripes and a red lantern. The lighthouse was built on the grounds of the Santa Marta Fort, which now houses a lighthouse museum. History The Fort of Santa Marta was probably built in the 1640s, later than of the other fortresses that are distributed along the coast of Cascais, since it was not mentioned in the inventory of forts of Cascais made in 1646. This fortress was built with the intention of preventing the approach of enemies to the Cascais Bay area. In the second half of the eighteenth century the fortress was the object of additional work, the most significant being that of 1762–1763, during which the parapet was widened, and that of 1793, in which battery spaces and quarters were ...
