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.
The Metropolitan Correctional Center, Chicago is a United States federal prison in Chicago, Illinois, United States. It holds imprisoned men and women of all security levels before and during court proceedings in the Northern District of Illinois, and for brief sentences. It is operated by the Federal Bureau of Prisons, a division of the United States Department of Justice.

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.
van der Rohe, 1964/1975
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.

Burnham & Root, 1888
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.
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.
961 ft. For a time this was the tallest building in the world without an official name, although locals know exactly what to call it: The White Castle Building. It is distinctive for its "crown," which is brightly illuminated at night. If you are nearby, head into its lobby to see its enormous indoor garden and fountain.
