The Fidelity Trust Building, also known as Swan Tower, is a 160,000-square-foot (15,000 m2)[1] commercial Renaissance Revival office building located at 284 Main Street in the Joseph Ellicott Historic District (also called the Downtown Historic District) in downtown Buffalo, New York.

The site of the current building was once referred to as "The Weed Block", (located at Main & Swan) and was built in 1857.

The block was home to Millard Fillmore's law office and other prominent Buffalo businessmen.

Harriman and a group of investors including A. H. Schoellkopf and James Forrestal, who would become the first United States Secretary of Defense, owned enough shares to control both Fidelity and M&T.
