The Cleveland Trust Tower was built in 1971 to accomodate the offices of Cleveland Trust. Noted Modern architect Marcel Breuer was responsible for the design. Breuer was initially widely known for his efforts in furniture design. Other buildings designed by Breuer include the Whitney Museum of American Art in New York City.

The tower's entrance is located on East Ninth Street, though its address is listed as 900 Euclid. The facade of the structure is composed primarily of black granite and concrete window forms which create a distinctive presence on the downtown skyline. The southern facade features a "cut out" on the tower's cornice. The original plans for the tower included a "twin" to be constructed on the site of the 1010 Euclid Avenue building. Those plans never materialized - however the existing tower retains infrastructure which would have been utilized by tenants in the second phase.

The Cleveland Trust bank eventually became Ameritrust. Ameritrust was acquired by Society Bank, which merged with KeyBank. The tower is adjacent to the historic Cleveland Trust Rotunda, a landmark designed by George B. Post. When the tower and Rotunda were no longer used, the buildings sat vacant for almost a decade. The entire complex (Tower, Rotunda, low-rise building, and parking garage) was purchased in September 2005 for $21,700,000 by the Cuyahoga County commissioners as the location of the new county administrative center. After solicting proposals from a limited pool of architecture firms, the commissioners selected a team comprised of Kohn, Pedersen, Fox and Cleveland-based Robert P. Madison International. This group's proposal included the demolition of the Cleveland Trust Tower on the grounds that the tower's floorplates are inefficient and that a newer structure would be aesthetically more appealing. Opponents of demolition suggested that the tower is an important landmark by a well-regarded architect, and that preservation would result in substantial savings of taxpayer funds. In addition, there are numerous sites in downtown Cleveland which would not require demolition of an existing structure.

In 2008, Cuyahoga County abandoned plans for a new administration complex, and the K&D Group purchased the Cleveland Trust Tower and adjacent buildings (including the historic rotunda). The complex will be converted into a mixed-use facility including a new 13-story office building to the south of the tower.
