The Rookery is gorgeous to the point of absurdity, with delight to be found in details in the rustic lower walls and the triumphant upper walls. (Note the helpful street names carved in the corners.) Named for pigeons' habit of roosting in the then-new skyscrapers, this was the first Loop building to be granted preservation status in 1972. The lobby was remodeled in 1907 by enfant terrible Frank Lloyd Wright, adding his own touch to the interior.
The Rookery Building is a historic office building at 209 South LaSalle Street in the Loop community area of downtown Chicago, Illinois, United States. Completed by architects Daniel Burnham and John Wellborn Root of Burnham and Root in 1888, it is considered one of their masterpiece buildings, and was once the location of their offices. The building is 181 feet (55 m) in height, twelve stories tall, and is considered the oldest standing high-rise in Chicago. It features exterior load-bearing walls and an interior steel frame. Inside is a light court, which illuminates a two-story atrium lobby with ornamental stairs. The building is designated a Chicago Landmark, and it is listed on the National Register of Historic Places as a National Historic Landmark.

Holabird & Roche, 1894
It's partially obscured by renovations, but this first-wave skyscraper still makes an immediate contrast with the modern Federal Center across the street. The lobby is decorated with Tiffany mosaics and bronze carvings of Pere Marquette, an early French explorer. There is plenty of first-floor retail to allow trips inside.

This plaza includes Mies' Dirksen Federal Building and Kluczynski Federal Building (built eleven years apart), with a low-rise post office enveloped in their sleek black lines. But the buildings are not quite as famous as the gigantic red constructivist flamingo statue by Alexander Calder in the plaza in front of the post office. An adventurous raccoon may have set a raccoon world climbing record by reaching the scaffolding on the 36th floor in 2006.
1007 ft. Built by Adrian Smith in 1989, the 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. It's not well-known, but it is the eighth tallest building in the U.S.
Burnham & Root, 1891
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). It's a masterpiece of simplicity and power in form. The block-long hallway that serves as a lobby has incredible ambiance: it's always kept at a level of brightness that suggests gas lamps, and the small stores on the first floor (a coffee shop, a shoe-shine, a restaurant) are all turn-of-the-century tile-and-polish.
287 ft. While not very tall, this 1975 brutalist structure is one of the most distinctive and curious in the Chicago skyline. As its name suggests, it is a vertical prison skyscraper and its sharp triangular shape is designed to minimize the amount of time that it takes to patrol its corridors. Its prisoners have some of the prison world's best views as their exercise yard is on top of the roof, although the narrow slits serving as windows do not allow such nice views from the cells. The prison houses male and female convicts of all security levels, waiting for transport to the courthouse nearby.
