Overview

The name Aon Center refers to two separate office skyscrapers in the United States that are identified by that corporate name. Both buildings have been associated with Aon, a global professional services and risk‑management firm, through tenancy or naming rights. Because the same name applies to more than one tower, it is important to specify the city when discussing a particular Aon Center.

Locations

Each Aon Center occupies a prominent downtown address in a different metropolitan area and functions as a visible corporate landmark in its skyline. Although the buildings share a brand identity, they are independent structures with distinct urban contexts, local histories and relationships to surrounding transit, retail and cultural institutions.

Architecture and materials

Both towers exemplify large, modern commercial office design, with rectilinear massing and floor plans organized to serve multiple tenants. Facade materials and detailing differ between the buildings: one tower displays a sleek, polished exterior typical of late twentieth‑century corporate towers, while the other reflects a different palette and set of design choices made at its time of construction and renovation. Internally, each structure includes elevator cores, mechanical floors and amenity spaces intended to support high‑density office use.

Naming and corporate tenancy

The Aon name appears on these towers as a result of corporate occupancy and naming‑rights arrangements. In commercial real estate, major tenants often secure naming prominence as part of lease or sponsorship agreements; conversely, when anchor tenants change, building names may be updated. In both cases, the building name serves as a form of corporate branding that links a company’s public identity to a city’s built fabric.

Function and urban role

Primarily designed for office use, each Aon Center houses professional services firms, supporting businesses and building amenities. As major downtown addresses, they contribute to local employment density, attract street‑level commerce and serve as navigational landmarks. Their presence influences surrounding development patterns and can be a factor in transit planning and neighborhood activity.

Distinguishing the towers

  • Specify the city: Because the same corporate name is used in multiple locations, always identify which city you mean to avoid confusion.
  • Expect architectural differences: Although both are commercial towers, materials, height, crown treatment and plaza design vary by building and era.
  • Names may change: Building names tied to tenants are not always permanent; historical names and former anchor tenants are part of each tower’s identity.

Understanding Aon Center as a name applied to distinct structures clarifies discussions about corporate real estate and urban landmarks. When researching or visiting an Aon Center, consult local sources for specifics about that city's tower, including current tenancy, access, public spaces and any recent renovations or signage changes.
