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.

The Loop initially got its name from the looping route of streetcars that served as the transit hub of early downtown Chicago, but the name has come to be defined by the modern era's looping route of elevated train tracks, serving seven CTA lines, which ensures the continued prominence of the area as the center of Chicago's working world.

On a work day, you won't have to walk around long to realize you are at the center of things. Busy-looking people in suits hurry in and out of tall buildings, major theaters hawk their big-name productions on neon marquees. The Loop is the United States' second largest central business district, owing largely to its historical position as the financial hub for the Midwest and as the modern world's biggest futures market.

In addition to Central Business district the Loop also has the fun of Millennium Park and the festivals of Grant Park and the amazing Art Institute.Museum campus is also located close by and is the home to the Shedd aquarium, Adler Planetarium, and the Field Museum of Natural History. A walk by the Sears Tower and the Chicago Board of Trade is a requisite Chicago experience, but the Loop is eclipsed by other parts of the city in terms of nightlife, shopping, and dining.
