In 1998, the European Central Bank was formed by 18 EU members with their headquarters in this 40 story Eurotower in Frankfurt, Germany. Below it is this blue and yellow, 49 foot Euro logo sculpture created in 2001 by Ottmar Höri. But if you hope to see the sculpture during your trip to Frankfurt you might be disappointed because there is a rumor that it may be sold soon in an auction. Plus, the ECB plans to move into new offices in 2014.
