Westhafen Tower is a 112.3 m (368 ft)[5] 30-storey skyscraper in the Gutleutviertel district of Frankfurt, Germany.

From the outside, the building is shaped like a cylinder, but the storeys are square-shaped, creating 18 conservatories between the interior and exterior.

One of the architectural features is the rhomboid facade structure, with 3556 triangular panes of glass forming the outer skin.

(see Geripptes [de]) A portion of the triangular segments of the glass can be automatically opened for ventilation purposes in the bottom corner.

Westhafen Tower houses the headquarters of the European Insurance and Occupational Pensions Authority.
