The Hansahochhaus is a skyscraper in the Neustadt-Nord quarter of north-central Cologne. When constructed in 1924-25 it was the city's first skyscraper, and one of the first skyscrapers in Germany. It was designed as an office building in the Expressionist style by the local architect, Jacob Koerfer . It was constructed in just 135 working days, which was considered less than the time taken to erect comparable buildings in the United States where skyscrapers were already becoming mainstream by the 1920s, but construction of the Hansahochhaus was subject to interruptions so the total construction period stretched over 15 months. With 17 floors and a total height of 65 meters, for a brief period following its construction the Hansahochhaus was Europe's tallest building [1] [2]
A skyscraper is a continuously habitable high-rise building that has over 40 floors and is taller than approximately 150 m (492 ft). Historically, the term first referred to buildings with 10 to 20 floors in the 1880s. The definition shifted with advancing construction technology during the 20th century. Skyscrapers may host commercial offices or residential space, or both. For buildings above a height of 300 m (984 ft), the term "supertall" can be used, while skyscrapers reaching beyond 600 m (1,969 ft) are classified as "megatall".
Cologne is the largest city of Germany's most populous federal state of North Rhine-Westphalia, and its 1 million+ (2016) inhabitants make it the fourth most populous city in Germany after Berlin, Hamburg, and Munich. The largest city on the Rhine, it is also the most populous city both of the Rhine-Ruhr Metropolitan Region, which is Germany's largest and one of Europe's major metropolitan areas, and of the Rhineland. Centred on the left bank of the Rhine, Cologne is about 45 kilometres (28 mi) southeast of North Rhine-Westphalia's capital of Düsseldorf and 25 kilometres (16 mi) northwest of Bonn. It is the largest city in the Central Franconian and Ripuarian dialect areas.
Expressionist architecture is an architectural movement in Europe during the first decades of the 20th century in parallel with the expressionist visual and performing arts that especially developed and dominated in Germany. Brick Expressionism is a special variant of this movement in western and northern Germany and in The Netherlands. Expressionist architecture is one of the three dominant styles of Modern architecture.
It is currently protected under historic monument legislation.
Cultural heritage management (CHM) is the vocation and practice of managing cultural heritage. It is a branch of cultural resources management (CRM), although it also draws on the practices of cultural conservation, restoration, museology, archaeology, history and architecture. While the term cultural heritage is generally used in Europe, in the USA the term cultural resources is in more general use specifically referring to cultural heritage resources. CHM has traditionally been concerned with the identification, interpretation, maintenance, and preservation of significant cultural sites and physical heritage assets, although intangible aspects of heritage, such as traditional skills, cultures and languages are also considered. The subject typically receives most attention, and resources, in the face of threat, where the focus is often upon rescue or salvage archaeology. Possible threats include urban development, large-scale agriculture, mining activity, looting, erosion or unsustainable visitor numbers. The public face of CHM, and a significant source of income to support continued management of heritage, is the interpretation and presentation to the public, where it is an important aspect of tourism. Communicating with government and the public is therefore a key competence.
