Great Central Station, also known as Great Central Depot, was an intercity train station in Chicago, Illinois owned by the Illinois Central Railroad (IC). It opened in 1856 and for a time was the largest building in downtown Chicago. Its passenger depot building was located on Water Street. In offices above the depot the IC had its headquarters, while beyond the depot was the large rail house where eight track lines ran. It was damaged in the Great Chicago Fire of 1871 but remained in operation. The station proved inadequate to handle growing traffic and its original building was demolished in 1893 in favor of the new Central Station further south. Although it continued to receive some traffic, over-time it increasingly became a commuter rail depot. Millennium Station, formerly Randolph Street Terminal, sits on the location.

Millennium Station (formerly Randolph Street Terminal; sometimes called Randolph Street station or Randolph/South Water Street station) is a major commuter rail terminal in the Loop (downtown), Chicago. It is the northern terminus of the Metra Electric District to Chicago's southern suburbs, and the western terminus of the South Shore Line to Gary and South Bend, Indiana. Located under Millennium Park, the terminal is a stub-end station and was established in the 1800s by the Illinois Central Railroad (IC) and has gone through several re-configurations. Most recently, it was rebuilt in the early 21st century and is owned by Metra through its operating arm, the Northeast Illinois Regional Commuter Railroad Corporation. Not counting commuters on the South Shore Line, over 18,000 people board Metra trains at Millennium Station each day. During peak periods, trains leave the terminal as frequently as twice a minute.

The Joan W. and Irving B. Harris Theater for Music and Dance (also known as the Harris Theater for Music and Dance, the Harris & Harris Theater or, most commonly, the Harris Theater) is a 1,499-seat theater for the performing arts located along the northern edge of Millennium Park on Randolph Street in the Loop community area of Chicago in Cook County, Illinois, US. The theater, which is largely underground due to Grant Park-related height restrictions, was named for its primary benefactors, Joan and Irving Harris. It serves as the park's indoor performing venue, a complement to Jay Pritzker Pavilion, which hosts the park's outdoor performances. Constructed in 2002–2003, it provides a venue for small and medium-sized music and dance groups, which had previously been without a permanent home and were underserved by the city's performing venue options. Among the regularly featured local groups are Joffrey Ballet, Hubbard Street Dance Chicago, and Chicago Opera Theater. It provides subsidized rental, technical expertise, and marketing support for the companies using it, and turned a profit in its fourth fiscal year. The Harris Theater has hosted notable national and international performers, such as the New York City Ballet's first visit to Chicago in over 25 years (in 2006). The theater began offering subscription series of traveling performers in its 2008–2009 fifth anniversary season. Performances through this series have included the San Francisco Ballet, Mikhail Baryshnikov, and Stephen Sondheim. The theater has been credited as contributing to the performing arts renaissance in Chicago and has been favorably reviewed for its acoustics, sightlines, proscenium and for providing a home base for numerous performing organizations. Although it is seen as a high caliber venue for its music audiences, the theater is regarded as less than ideal for jazz groups because it is more expensive and larger than most places where jazz is performed. The design has been criticized for traffic flow problems, with an elevator bottleneck. However, the theater's prominent location and its underground design to preserve Millennium Park have been praised. Although there were complaints about high priced events in its early years, discounted ticket programs were introduced in the 2009–10 season.
