Tjärven
Tjärven is the name of a small island and light station surrounded by deep water and located in the sea of Åland, north of the Söderarm archipelago of the coast of Sweden. The lighthouse functions as the entrance to the shipping route for the ports of Kapellskär, Norrtälje and Stockholm. History A day beacon existed on the island since the 19th century. The lighthouse construction began in 1902, and was finished in 1903. The original architecture included a crenelated gallery and an old-style lantern room. The building included bedrooms and a kitchen area for the lighthouse keepers. The light ran on kerosene. In 1952, the building was renovated and was redesigned in a functionalistic style with eternit bricks. The lantern was also changed and a 1000 watt electric light replaced the kerosene lamp. The Swedish Maritime Administration owns and runs the lighthouse. It renovated the building in 2008 and installed solar power. Initially, there was a decision to remove the lanter ...

Söderarm
Söderarm is the name of a deactivated Swedish lighthouse station and its surrounding small archipelago in the west part of the Sea of Åland. The light station is located on the island of Thorskär. This area, together with the tiny island of Tjärven north of Söderarm, marks the entrance for the shipping route leading to the ports of Kapellskär, Norrtälje, and also the north entrance to Stockholm. The area has been severely fortified by the Swedish military and coastal artillery, and many traces of military activity from the years during the second world war are still visible. On the island of Manskär, for example, a large military radar mast stood for many years. It was demolished in 2010. In 2002, the coastal artillery was formally liquidated at Söderarm, but still some islands are forbidden for the public to visit. The Swedish Maritime Administration has confirmed that many Russian mines dating from the First World War may still lie on the sea bottom east of the light s ...

Sea Of Åland
The Åland Sea (or the Sea of Åland; sv, Ålands hav, fi, Ahvenanmeri) is a waterway in the southern Gulf of Bothnia, between Åland and Sweden. It connects the Bothnian Sea with the Baltic Sea proper. The western part of the basin is in Swedish territorial waters while the eastern part is in Finnish territorial waters. The Åland Sea has two sub-basins. The main basin is the Åland Sea proper, also called the northern Åland Sea basin. In the south, there is the smaller Lågskär Deep, also called the Lågskär Basin or the southern Åland Sea basin. The narrowest part on the northern edge of the basin is named the Southern Quark or South Kvarken ( sv, Södra Kvarken, fi, Ahvenanrauma). The trench running on the bottom of the Sea of Åland contains the second-deepest spot of the Baltic Sea, at a depth of 301 meters, which is second only to Landsort Deep. The mean depth of Åland Sea is 75 m, area 5,477 km2 and its volume is 411 km³. The Archipelago Sea and th ...

Shipping Route
A sea lane, sea road or shipping lane is a regularly used navigable route for large water vessels (ships) on wide waterways such as oceans and large lakes, and is preferably safe, direct and economic. During the Age of Sail, they were determined by the distribution of land masses but also by the prevailing winds, whose discovery was crucial for the success of long maritime voyages. Sea lanes are very important for seaborne trade. History The establishment of the North Atlantic sea lanes was inspired by the sinking of the US mail steamer SS ''Arctic'' by collision with the French steamer SS ''Vesta'' in October 1854 which resulted in the loss of over 300 lives. Lieutenant M. F. Maury of the US Navy first published a section titled "Steam Lanes Across the Atlantic" in his 1855 ''Sailing Directions'' proposing sea lanes along the 42 degree latitude. A number of international conferences and committees were held in 1866, 1872, 1887, 1889, and 1891 all of which left the designat ...

Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning " wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States.

Functionalism (architecture)
In architecture, functionalism is the principle that buildings should be designed based solely on their purpose and function. This principle is a matter of confusion and controversy within the profession, particularly in regard to modern architecture, as it is less self-evident than it first appears. The theoretical articulation of functionalism in buildings can be traced back to the Vitruvian triad, where ''utilitas'' (variously translated as 'commodity', 'convenience', or 'utility') stands alongside ''firmitas'' (firmness) and ''venustas'' (beauty) as one of three classic goals of architecture. Functionalist views were typical of some Gothic Revival architects. In particular, Augustus Welby Pugin wrote that "there should be no features about a building which are not necessary for convenience, construction, or propriety" and "all ornament should consist of enrichment of the essential construction of the building". In the wake of World War I, an international functionalist ar ...

Eternit
Eternit is a registered trademark for a brand of fibre cement currently owned by the Belgian company Etex. Fibre is often applied in building and construction materials, mainly in roofing and facade products. Material description The term "cement" originates from the Latin word "''Caementum''", which signifies chopped stone. Cement describes a binding substance, which will react chemically with water and develop into a material hard as stone. In fibre cement there is a fibre reinforcement, which contributes to making the fibre-cement material even stronger and to better withstand tension. Together with a carefully planned production process, fibre cement makes it possible to develop strong and long-lasting construction materials. Today fibre cement is considered as a material physically suited for construction products such as cladding and roofing. Material history Fibre-reinforced cement-products were invented in the late 19th century by the Austrian Ludwig Hatschek. Pri ...
