Because of the limited space in the Eurotower the personnel of the ECB were also (up to March 2015) distributed between two other skyscrapers in the Bankenviertel, the Eurotheum and Neue Mainzer Straße 32–36.

This was considered less than optimal, so in the late 1990s the ECB began a process to have a new seat built on a site in the eastend of Frankfurt.

In November of that year bank personnel started to transfer from the Eurotower to their new offices at the Seat.

The building has since been hosting the European Central Bank's supervisory arm, with around 1,400 employees working from the site.
