East german tower

The erection of Tower West was the first stage of the entire Federation complex construction, but the height of the tower was increased in comparison with the original models (originally, Tower West was planned to be half the height of Tower East). The cross-section of the tower's core, originally planned to be hexagonal, was modified after construction began and is now trapezoidal. The core was constructed so it rose above the rest of the structure, which was assembled one or two floors behind. The building was completed in early 2008.

Starting with the 1 Pf. in 1960, followed by the 10 Pf. in 1963, and the 5 Pf. in 1968, the old style coins were gradually replaced with new coins depicting the state name "Deutsche Demokratische Republik." Aluminium 1 Mark, 2 Mark and 50 Pfennig pieces were released for circulation in 1956, 1957 and 1958, respectively. In 1969, brass 20 Pfennig coins were introduced, with nickel-bronze (later cupro-nickel) 5 Mark coins issued from 1968. In 1973 and 1974, 1 and 2 Mark coins were redesigned dropping the former "Deutsche Mark" title. The brass 20 Pfennig coins were issued partly because pay telephones had a standard charge of 20 Pf. and were having problems with smaller aluminium coins jamming due to their light weight. Commemorative 5, 10, and 20 Mark coins of various types have also occasionally made it into circulation.

A helical skyscraper that makes a distinct mark on the Dubai skyline, Cayan Tower is at once remarkable and subtle. The residential tower is a pure expression of the idea that a building’s form should directly follow its structural framework.

While the skyscraper’s 73 floorplates are all identical, each is slightly rotated against the story below it, resulting in a full 90-degree twist over the course of the tower's 307-meter rise. The benefits of this unique form, besides the aesthetic ones, are manifold. Wind load and solar heat gain are reduced compared to a rectilinear building of the same height, and a greater number of tenants are afforded desirable views of the nearby marina and gulf.
