The Mellon National Bank Building at 500 Smithfield Street in downtown Pittsburgh, Pennsylvania, was completed in 1924 after Mellon acquired the property in August 1916 from the Baltimore & Ohio Railroad which had their regional offices on the site.[3]
On July 30, 1999, May & Co. bought the structure for $9.250 million from Mellon.[5] The building's historic interior was gutted and converted into a department store despite the protests of historical preservationists. It opened as Lord & Taylor on November 1, 2000, after a $12 million refurbishment (21.2 million in 2023 dollars).[6] Lord & Taylor closed just four years later, in 2004.
On May 31, 2012 PNC Financial Services purchased the structure[7] and converted it to a call center.[8] In 2024, PNC announced their intention to sell the building.[9]
