The former Steam Concourse of Cleveland Union Terminal survives but in a much altered form. The original segmental-arched ceiling and skylight were removed as part of the Tower City Center project and were replaced with this barrel-vaulted concourse that features abundant natural light and a large fountain. Though the space bears little resemblance to the original concourse, features such as original marble flooring and classical columns have been retained. The old Union Terminal remains the center of rail transportation in Cleveland, even though that currently consists only of transit lines. (Jeffrey T. Darbee)
