Riverview
Also known as: Fiberglas Tower, Levis Square, Riverview One, HyTower,; Tower on the Maumee
Why it's listed
Riverview is a downtown Toledo complex of three parts: a 28-story glass-and-aluminum office tower completed in 1969, a five-story precast concrete parking garage with 415 spaces, and Levis Square, a city-owned plaza built around a square concrete fountain. All were built in 1967 to 1970 under a master plan by I. M. Pei for an urban renewal project. Harrison and Abramovitz designed the tower, a late example of the International Style glass box, with a brick service core and a recessed clear-glass first floor that gives a floating look. The complex mattered locally because it was the only part of the Riverview renewal plan built much as Pei envisioned. It also housed the Owens-Corning Fiberglas headquarters for more than two decades, during major growth and a takeover fight in the 1980s. The exterior and plaza retain high integrity, though the tower interior has lost many finishes and the building is currently vacant.
Significance in brief: The nomination argues Riverview was the centerpiece and most fully realized part of Toledo's highest-profile downtown urban renewal project, planned by I. M. Pei. It also served for over 20 years as headquarters of Owens-Corning Fiberglas, and the tower is regarded as the city's most significant Modernist landmark, designed by Harrison and Abramovitz.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
