Frankfurt: ECB HQ

One of the 606 ft. tall twin towers along the Main —at the former site of the Grossmarkthalle [the wholesale market hall] in the city's Ostend district— topped out in 2012 and inaugurated in 2015, is part of the European Central Bank headquarters.  The earlier headquarters, the Eurotower at Willy-Brandt-Platz in the Innenstadt, is home to an affiliate institution, the Single Supervisory Mechanism.
