The Deutsche Bank Twin Towers, also known as Deutsche Bank Headquarters (German: Zwillingstürme der Deutschen Bank or Hauptverwaltung Deutsche Bank AG), is a twin tower skyscraper complex in the Westend-Süd district of Frankfurt, Germany. Both towers rise to and serve as headquarters for Deutsche Bank, the largest bank in Germany. Location The Deutsche Bank Twin Towers are prominently located at the borders of the city districts of Westend-Süd, the Bahnhofsviertel and the Innenstadt, near a series of baroque-era-fortifications-gone-parks (Wallanlagen) and the Opernplatz. This area forms Frankfurts central business district called Bankenviertel. The twin towers are part of a chain of high-rise buildings at Mainzer Landstraße which stretches from the Opernplatz in the east to the Platz der Republik in the west. The towers have direct access to an underground S-Bahn station (Taunusanlage). The largest man-shaped monolith of the world, created by the Swiss sculptor Max Bill, is located in front of the entrance. Architecture The towers were built from 1979 to 1984 originally to house a hotel for the Hyatt Hotel Group. The buildings were already under construction when Hyatt cancelled its plans and Deutsche Bank decided to locate its headquarters there. The complex consists of three parts: a four-storey base building and the two towers. The buildings are complete reinforced concrete structures with reflective glass facades. In contrast to the neighboring high-rise Trianon, built a few years later, the pedestal of the Deutsche Bank skyscraper adapts to the urban environment. It is lower than the neighboring buildings, but spread out over a large base area. From the center of the plant, between the two towers, stretch on an irregular floor plan three components to the east, southwest and northwest. The towers are irregular trapezoidal shapes, but both feature identical floors plans that have symmetric 45-degree angles arranged from the center of the plant around. The buildings have become a popular backdrop in print media and television as a symbol for the German economy because of the role that Deutsche Bank plays as one of the most important global banking and financial services companies. Construction The towers share a foundation slab, which is thick in the middle and tapers towards the edges to . The panel consists of of reinforced concrete. The formation depth is approximately below ground level. Renovation In 2006, Deutsche Bank decided that the towers would undergo a major renovation after 22 years due to changes in
