Tower City Center (formerly known as Cleveland Union Terminal) is a large mixed-use facility located on Public Square in downtown Cleveland. The facility is comprised of a number of interconnected office buildings including the landmark Terminal Tower, a shopping mall, two hotels, and the main hub of Cleveland's three rapid transit lines.

The Cleveland Union Terminal was built in 1927 by the Van Sweringen brothers as a terminus for all trains coming into Cleveland in a concept similar to New York City's Grand Central Station. The facility also included a number of retail stores and restaurants. Original designs for the complex show that at first the brothers did not plan on building an office tower within the complex. However, they eventually decided to build the 52-story Terminal Tower on the northeast side of the complex facing Public Square. From its completion until 1967, the Terminal Tower was the tallest building in the world outside of New York City.
