AT&T Corporate Center

Built by Adrian Smith in 1989, the 1007 feet tall granite-clad AT&T Corporate Center is one of the city's more distinctive skyscrapers for its massive size, spiked roof pinnacles, and a style evocative of both Gothic and Japanese architectural styles

Monadnock Building

Named appropriately for a mountain in New Hampshire, the Monadnock was the last tall building to be supported by its own walls (not a metal frame, although the 1893 addition by Holabird & Roche does use one)

Marquette Building

It's partially obscured by renovations, but this first-wave skyscraper still makes an immediate contrast with the modern Federal Center across the street
