Bogskär Lighthouse
Bogskär Lighthouse () is located on the Bogskär, Bogskär skerries of Åland. History The lighthouse was constructed in the 1870s and was completed in 1882, on Sweden's initiative. Of steel construction, it was erected on a three-metre granite plinth. The red-painted lighthouse had seven floors. The lighthouse had a crew of nine, of which half were occupying the lighthouse at a time. The lighthouse was damaged in a storm during the winter of 1889. In an 1894 repair, it was strengthened and to add weight, the space between its inner and outer shells was filled in with concrete up to the third floor. In 1905, a wireless telegraph was installed, replacing the previous communication via light signals to passing ships. In 1915 under the First World War, a German warship destroyed the original lighthouse. A new automated lighthouse was constructed in 1922 on concrete pillars. The lighthouse was restored in 1981, when it was equipped with a helipad. The lighthouse is now painted b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogskär
Bogskär is a small group of Baltic Sea islets off the southernmost tip of Finland. It is Finland's southernmost land and governed by the municipality of Kökar in Åland. The islets are remote: the distance to the nearest large islands in Kökar, Föglö and Lemland is over . Bogskär is so remote that it is located outside the internal waters of Finland, and has its own, separate internal waters. Up to 1995, even its territorial waters were separate from the rest of Finland. When the territorial waters were expanded from a limit of to , the territorials waters merged. Even today, territorial waters extend only south of Bogskär.

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by the countries of Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden, and the North European Plain, North and Central European Plain regions. It is the world's largest brackish water basin. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. It is a Continental shelf#Shelf seas, shelf sea and marginal sea of the Atlantic with limited water exchange between the two, making it an inland sea. The Baltic Sea drains through the Danish straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia (divided into the Bothnian Bay and the Bothnian Sea), the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The "Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the ...

Finland
Finland, officially the Republic of Finland, is a Nordic country in Northern Europe. It borders Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland to the south, opposite Estonia. Finland has a population of 5.6 million. Its capital and largest city is Helsinki. The majority of the population are Finns, ethnic Finns. The official languages are Finnish language, Finnish and Swedish language, Swedish; 84.1 percent of the population speak the first as their mother tongue and 5.1 percent the latter. Finland's climate varies from humid continental climate, humid continental in the south to boreal climate, boreal in the north. The land cover is predominantly boreal forest biome, with List of lakes of Finland, more than 180,000 recorded lakes. Finland was first settled around 9000 BC after the Last Glacial Period, last Ice Age. During the Stone Age, various cultures emerged, distinguished by differen ...

Ã…land
Åland ( , ; ) is an Federacy, autonomous and Demilitarized zone, demilitarised region of Finland. Receiving its autonomy by a 1920 decision of the League of Nations, it is the smallest region of Finland by both area () and population (30,541), constituting 0.51% of Finland's land area and 0.54% of its population. Its only official language is Swedish language, Swedish and the capital city is Mariehamn. Åland is situated in an archipelago, called the Åland Islands, at the entrance to the Gulf of Bothnia in the Baltic Sea. It comprises Fasta Åland, on which 90% of the population resides, and about 6,500 Skerry, skerries and islands to its east, of which about 60–80 are inhabited. Fasta Åland is separated from the coast of Roslagen in Sweden by of open water to the west. In the east, the Åland archipelago is Geographic contiguity, contiguous with the Archipelago Sea, Finnish archipelago. Åland's only land border is located on the uninhabited skerry of Märket, which it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plinth
A pedestal or plinth is a support at the bottom of a statue, vase, column, or certain altars. Smaller pedestals, especially if round in shape, may be called socles. In civil engineering, it is also called ''basement''. The minimum height of the plinth is usually kept as 45 cm (for buildings). It transmits loads from superstructure to the substructure and acts as the retaining wall for the filling inside the plinth or raised floor. In sculpting, the terms base, plinth, and pedestal are defined according to their subtle differences. A base is defined as a large mass that supports the sculpture from below. A plinth is defined as a flat and planar support which separates the sculpture from the environment. A pedestal, on the other hand, is defined as a shaft-like form that raises the sculpture and separates it from the base. An elevated pedestal or plinth that bears a statue, and which is raised from the substructure supporting it (typically roofs or corniches), is some ...

Wireless Telegraph
Wireless telegraphy or radiotelegraphy is the transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term ''wireless telegraphy'' was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. It continued to be the only type o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouses Completed In 1882
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), 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 the advent of much cheaper, more sophisticated, and more 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 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 promontory, prom ...
