The Loop is the central business district of Chicago, bounded by the Chicago River to the north and west, Harrison Street to the south, and Lake Michigan to the east. It contains the tallest members of Chicago's skyline and much of the city's finest architecture, holding within them much of the city's working stiffs; for visitors, it also has the glitzy downtown theater district, and the biggest annual music festivals.
The Loop is the center of Chicago and without a doubt the most iconic section of the city. If you've never been to Chicago, begin here. Whether on an official architecture cruise along the Chicago River, or an unofficial one along the veritable river of elevated trains, only the most jaded could shake that feeling of awe at the canyons of LaSalle and the cliffs of Michigan Avenue. Moreover, the Loop contains a world-class collection of public art, in the form of huge street-side statues by many of the 20th century's most famous sculptors.
