Different types of tower were developed and built at different locations, like the series FMT 1 to FMT 16. The individual series differ in each case in the number of antenna platforms and the size of the operating projectile. The types FMT 7 to 10 are without pulpit. The type towers were usually designed on the basis of economic and functional criteria and only secondarily for aesthetics. Compared with structural steelworks, the reinforced concrete construction way is easier in the establishment and maintenance. In Germany there are about 300 towers of this type.
The establishment of these towers began in the mid-1960s, when the Federal Postal Administration developed its radio relay system clearly. In the planning of the type towers engineer Fritz Leonhardt and the architect Erwin Heinle were considerably involved.
The communications towers in Münster, Kiel, Bremen and Cuxhaven were planned by an architect of the regional directorate Kiel and actually do not belong to this type of tower. They are therefore called Sondertürme, to which e.g. also the Rheinturm, the Heinrich-Hertz-Turm and the Fremersbergturm belong. In addition, the telecommunication tower Koblenz reminded strongly of the type towers FMT 11 to 13, is a special tower, since it is larger substantially more highly and the pulpit than with the type towers.
Charles-Édouard Jeanneret, known as Le Corbusier, was a Swiss-French architect, designer, painter, urban planner, writer, and one of the pioneers of what is now regarded as modern architecture. He was born in Switzerland and became a French citizen in 1930. His career spanned five decades, and he designed buildings in Europe, Japan, India, and North and South America.
A skyscraper is a tall continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least 100 metres (330 ft) or 150 metres (490 ft) in height, though there is no universally accepted definition. Skyscrapers are very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces.
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion.
Modern architecture, or modernist architecture, was an architectural movement or architectural style based upon new and innovative technologies of construction, particularly the use of glass, steel, and reinforced concrete; the idea that form should follow function (functionalism); an embrace of minimalism; and a rejection of ornament. It emerged in the first half of the 20th century and became dominant after World War II until the 1980s, when it was gradually replaced as the principal style for institutional and corporate buildings by postmodern architecture.
Air raid shelters are structures for the protection of non-combatants as well as combatants against enemy attacks from the air. They are similar to bunkers in many regards, although they are not designed to defend against ground attack.
Eugène Freyssinet was a French structural and civil engineer. He was the major pioneer of prestressed concrete.
The Florianturm is a telecommunications tower and landmark of Dortmund (Germany). It is named after St. Florian, the patron saint of gardeners.
Flak towers were large, above-ground, anti-aircraft gun blockhouse towers constructed by Nazi Germany. There were 8 flak tower complexes in the cities of Berlin (three), Hamburg (two), and Vienna (three) from 1940 onwards. Other cities that used flak towers included Stuttgart and Frankfurt. Smaller single-purpose flak towers were built at key outlying German strongpoints, such as at Angers in France, and Helgoland in Germany.
Notre-Dame du Haut is a Roman Catholic chapel in Ronchamp, France. Built in 1955, it is one of the finest examples of the architecture of Franco-Swiss architect Le Corbusier. The chapel is a working religious building and is under the guardianship of the private foundation Association de l’Œuvre de Notre-Dame du Haut. It attracts 80,000 visitors each year. In 2016, it was inscribed on the UNESCO World Heritage List in along with sixteen other works by Le Corbusier, because of its importance to the development of modernist architecture.
Aarberg is a historic town and a municipality in the Seeland administrative district in the canton of Bern in Switzerland.
The Alte Weser Lighthouse is located offshore from the estuary mouth of the river Weser in the German Bight, southern North Sea. It was built on sand between 1961 and 1964. The lighthouse took over duties and replaced the historical Roter Sand Lighthouse on 1 September 1964. The latter had been built from 1883 to 1885.
The Church of Holy Trinity is a church in Mošovce. In the past, the gothic church had a tower, which was the dominant feature of its surroundings, and it belonged to the most monumental sacral buildings in Turiec.
Kaiserliche Werft Danzig was a German shipbuilding company founded in 1852 as Königliche Werft Danzig and renamed Kaiserliche Werft after the proclamation of the German Empire in 1871. Together with Kaiserliche Werft Kiel and Kaiserliche Werft Wilhelmshaven it was one of three shipyards responsible for maintenance, repair and construction of warships for the Imperial German Navy. Kaiserliche Werft Danzig closed in 1918 after the end of World War I, but soon opened when Danziger Werft was founded on its site in 1919.
The Hampden County Memorial Bridge is a reinforced-concrete arch bridge that spans the Connecticut River between Springfield, Massachusetts and West Springfield, Massachusetts, constructed in 1922. The bridge is owned by Massachusetts Highway Department and is located on Massachusetts Route 147. It spans 209 feet (64 m) and rises 29.71 feet (9.06 m) above the river.
Esch-sur-Sûre Castle, now a ruin, is located on a spur in the small town of Esch-sur-Sûre in the north-west of Luxembourg. It is naturally protected by a sharp meander in the River Sûre which surrounds the town and the castle on three sides.

The reservoir features various decorative attributes, plastered by hand, which lack in other functional reservoirs. Established in 1920, the reservoir serves a large area of South-Western Sydney.

Henri de Miffonis, born as Louis Fernand Henri de Miffonis, was a civil engineer. He was born in Boulogne-Billancourt, France and died in Canada in 1955. Miffonis specialized in the construction of lighthouses. He studied in civil engineering at the University of Paris. In 1905, after obtaining his diploma, he accepted an offer of employment with the Department of Fisheries and Oceans in Canada for work with the Commission des phares, newly created. Miffonis' work was supervised by the Chief Engineer of the Commission, William Patrick Anderson, a fervent promoter of reinforced concrete in the construction of lighthouses.
