The Carlyle is a 300 ft (91m) tall skyscraper at Fourth Avenue and Wood Street in Pittsburgh.

This 1906 neo-classical building was originally the Union National Bank Building,[1] designed by the architectural firm of MacClure & Spahr.

Benno Janssen, who was employed by that firm, had a key role in its design.

After many years of relatively low occupancy rates, the structure was converted into condominiums in 2006.
