Spin Tower, High-rise building in European Quarter, Frankfurt, Germany.

Spin Tower is a modern high-rise in the European Quarter with 31 floors that combines hotel and office spaces in a single building. The lower sections house an international hotel brand, while the upper floors provide office areas.

The site between Mainzer Landstrasse, Güterplatz and Europa-Allee lay fallow for around 20 years after a planned 160-metre office tower by owner Robert Bosch GmbH found no investor; in 2013 Bosch dropped the tower, and in 2015 sold the plot to ABG Frankfurt Holding, which passed the later Spin parcel to developer Groß & Partner. A 2016 competition was won by Jahn and Magnus Kaminiarz & Cie.; the groundbreaking took place on 29 May 2018, and the tower was completed in April 2023.

The tower's name was first presented in 2017 as Spin Tower before later being shortened to The Spin. Its lower 20 floors are occupied by the NH Collection Frankfurt Spin Tower hotel, which opened on 1 May 2023, while floors 22 to 31 hold around 10,000 square metres of offices.

The tower stands at Güterplatz, between Mainzer Landstrasse and Europa-Allee in the Europaviertel. A U5 underground station was planned next to the building, but as of April 2024 the line's completion into the Europaviertel was expected during 2027. The NH Collection hotel occupies the lower 20 floors, offices floors 22 to 31, with a roof terrace on the 32nd.

The tower was initially planned as "Tower 120" and only later renamed The Spin. Its office floors 22 to 31 cover around 10,000 square metres, with a roof terrace on the 32nd floor reserved for office tenants. The hotel in the lower 20 floors opened on 1 May 2023 as NH Collection Frankfurt Spin Tower.
