The Hessian metropolis earned the nickname German Manhattan at the turn of the millennium, thanks to skyscrapers of financial institutions soaring in the city center up to a quarter of a kilometer high. However, with the arrival of the global crisis, the construction boom came to a halt. In addition to the well-aired wallets of investors, the local authorities are responsible for height regulation. The latest Frankfurt landmark, the headquarters of the European Central Bank opened in March 2015, was built with a four-year delay, a budget that was overspent threefold, and reached a height of only 185 meters. The most active construction activities currently take place in the Marieninsel area on the western edge of downtown Frankfurt, in places of the historic fortifications between Taunusanlage Park and the River Main. Two years ago, the development company Pecan announced a competition for a new Marienturm complex with a forty-story landmark totaling 155 meters in height. The winning design from the Berlin studio Müller Reimann connects with the surrounding buildings through lower stepped structures. It also plans for a smaller commercial square that will introduce the entrance to the new landmark in the Frankfurt skyline. Construction work is beginning these days, which should be completed in 2019.
