Gallileo is a 446ft (136m) tall skyscraper in Frankfurt, Germany. It was constructed from 1999 to 2003 and has 38 floors. It has 49,000 m² of floor space and is the 14th tallest skyscraper in Frankfurt. Its name is an intentional misspelling of the scientist Galileo's name; the extra l comes from the building's other namesake, the nearby park Gallusanlage. Along with the nearby Silver Tower, it served as the corporate headquarters of Dresdner Bank since 2008. A year later, after the takeover of Dresdner Bank by Commerzbank, the new owner plans to use only the Gallileo. It has a glass facade with 400 individual windows forming an approximately 22,000 square metres large transparent outer skin. In the glass floors were the American artist James Turrell, integrated lighting, which make the building at night from the inside out "glowing". These are not architecturally visible. The undersides of the floor slabs serve as reflective surfaces. The building is structurally two towers linked by a central core that connects them. The north tower is 130 metres, the south tower is 114 metres, and the core is the building's full height. Some shops, a bar, and the English Theatre are located on the ground floor.
