The Eurotheum is a 31-storey, 110 m skyscraper in the city center of Frankfurt, Germany. The building was constructed in 1999 to coincide with the adjacent Main Tower, and is one of a few such in Frankfurt that offers office and residential space. Each floor of the tower has 17,000 m of office space, which has been occupied mostly by the European Central Bank as an extension of their headquarters at Willy-Brandt-Platz until 2015. The 22nd floor has a public bar lounge.
