Chicago's Iconic Supertall Dominates the Skyline

Once World's Tallest, Now a Towering Symbol of the City

A Story of Architectural Ingenuity and Civic Pride

Soaring high above the Windy City, the John Hancock Center has become an architectural icon and an inseparable part of Chicago's identity. As one of the first supertall buildings in the world, its innovative design and remarkable height forever changed the face of the city's skyline.

When it was completed in 1969, the John Hancock Center reigned supreme as the world's tallest reinforced concrete building, a testament to the ingenuity of architects Skidmore, Owings & Merrill. Its sleek, black exterior and signature X-bracing system not only gave it an unforgettable silhouette but also showcased the possibilities of modern construction.
