Tower Of Unity
The Tower of Unity (German: Turm der Einheit) is a observation tower on Heldrastein, a rocky mountain belonging to Treffurt in Thuringia. The tower of Unity has an unusual history and is also from unusual design, because it is additionally guyed by anchoring wires, although it is actually free standing. The tower of Unity was built in 1962 as transmitting tower for a radar station. At that time it was an open steel lattice tower additionally guyed with the radar facility on its top. The area of this tower was not accessible for tourists at those days as it laid in the restricted area of the former border between West and East Germany. In 1989, when the border was opened, the area became again accessible for the public and the desire developed to build on Heldrastein again an observation tower, as there was until 1952 an observation tower built of stones, the such called Carl Alexander tower there. In 1996 finally permission for the transformation of the radar tower into an observatio ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Observation Tower
An observation tower is a structure used to view events from a long distance and to create a full 360 degree range of vision to conduct long distance observations. Observation towers are usually at least tall and are made from stone, iron, and wood. Many modern towers are also used as TV towers, restaurants, or churches. The towers first appeared in the ancient world, as long ago as the Babylonian Empire. Observation towers that are used as guard posts or observation posts over an extended period to overlook an area are commonly called watchtowers instead. Construction and usage Observation towers are an easily visible sight on the countryside, as they must rise over trees and other obstacles to ensure clear vision. Older control rooms have often been likened to medieval chambers. The heavy use of stone, iron, and wood in their construction helps to create this illusion. Modern towers frequently have observation decks or terraces with restaurants or on the roof of mountain st ...

Treffurt
Treffurt () is a small town in the western region of the Wartburgkreis district which belongs to the federal state of Thuringia. The former municipality Ifta was merged into Treffurt in January 2019. The town lies near the Werra and is surrounded by the Werratal valley and rivers. Treffurt is located next to the Hessian border and was a former part of the Sperrzone. Today, Treffurt is a tourist destination, especially due to its scenic town centre with many restored half-timbered houses and its landmark - the Normannstein castle.

Thuringia
Thuringia (; german: Thüringen ), officially the Free State of Thuringia ( ), is a state of central Germany, covering , the sixth smallest of the sixteen German states. It has a population of about 2.1 million. Erfurt is the capital and largest city. Other cities are Jena, Gera and Weimar. Thuringia is bordered by Bavaria, Hesse, Lower Saxony, Saxony-Anhalt, and Saxony. It has been known as "the green heart of Germany" () from the late 19th century due to its broad, dense forest. Most of Thuringia is in the Saale drainage basin, a left-bank tributary of the Elbe. Thuringia is home to the Rennsteig, Germany's best-known hiking trail. Its winter resort of Oberhof makes it a well-equipped winter sports destination – half of Germany's 136 Winter Olympic gold medals had been won by Thuringian athletes as of 2014. Thuringia was favoured by or was the birthplace of three key intellectuals and leaders in the arts: Johann Sebastian Bach, Johann Wolfgang von Goethe, a ...

Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution ...

West Germany
West Germany is the colloquial term used to indicate the Federal Republic of Germany (FRG; german: Bundesrepublik Deutschland , BRD) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from eleven states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. The FRG's provisional capital was the city of Bonn, and the Cold War era country is retrospectively designated as the Bonn Republic. At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

East Germany
East Germany, officially the German Democratic Republic (GDR; german: Deutsche Demokratische Republik, , DDR, ), was a country that existed from its creation on 7 October 1949 until its dissolution on 3 October 1990. In these years the state was a part of the Eastern Bloc in the Cold War. Commonly described as a communist state, it described itself as a socialist "workers' and peasants' state".Patrick Major, Jonathan Osmond, ''The Workers' and Peasants' State: Communism and Society in East Germany Under Ulbricht 1945–71'', Manchester University Press, 2002, Its territory was administered and occupied by Soviet forces following the end of World War II—the Soviet occupation zone of the Potsdam Agreement, bounded on the east by the Oder–Neisse line. The Soviet zone surrounded West Berlin but did not include it and West Berlin remained outside the jurisdiction of the GDR. Most scholars and academics describe the GDR as a totalitarian dictatorship. The GDR was est ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Deutsche Mark
The Deutsche Mark (; English: ''German mark''), abbreviated "DM" or "D-Mark" (), was the official currency of West Germany from 1948 until 1990 and later the unified Germany from 1990 until the adoption of the euro in 2002. In English, it was typically called the "Deutschmark" (). One Deutsche Mark was divided into 100 pfennigs. It was first issued under Allied occupation in 1948 to replace the Reichsmark and served as the Federal Republic of Germany's official currency from its founding the following year. On 31 December 1998, the Council of the European Union fixed the irrevocable exchange rate, effective 1 January 1999, for German mark to euros as DM 1.95583 = €1. In 1999, the Deutsche Mark was replaced by the euro; its coins and banknotes remained in circulation, defined in terms of euros, until the introduction of euro notes and coins on 1 January 2002. The Deutsche Mark ceased to be legal tender immediately upon the introduction of the euro—in contras ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Radome
A radome (a portmanteau of radar and dome) is a structural, weatherproof enclosure that protects a radar antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by quickly rotating antennas. Radomes can be constructed in several shapes spherical, geodesic, planar, etc. depending on the particular application, using various construction materials such as fiberglass, polytetrafluoroethylene (PTFE)-coated fabric, and others. When found on fixed-wing aircraft with forward-looking radar, as are commonly used for object or weather detection, the nose cones often additionally serve as radomes. On aircraft used for airborne early warning and control (AEW&C), a rotating radome, often called a "rotodome", is mounted on the top of the fuselage for 360-degree coverage. Some newer AEW&C configurations inst ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stairs
Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles. Types of stairs include staircases (also called stairways), ladders, and escalators. Some alternatives to stairs are elevators (also called lifts), stairlifts, inclined moving walkways, and ramps. A stairwell is a vertical shaft or opening that contains a staircase. A flight (of stairs) is an inclined part of a staircase consisting of steps (and their lateral supports if supports are separate from steps). Components and terms A ''stair'', or a ''stairstep'', is one step in a flight of stairs.R.E. Putnam and G.E. Carlson, ''Architectur ...

Octagon
In geometry, an octagon (from the Greek ὀκτάγωνον ''oktágōnon'', "eight angles") is an eight-sided polygon or 8-gon. A ''regular octagon'' has Schläfli symbol and can also be constructed as a quasiregular truncated square, t, which alternates two types of edges. A truncated octagon, t is a hexadecagon, . A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. Properties of the general octagon The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external angles total 360°. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).Dao Thanh Oai (2015), "Equilatera ...
