Visitor Experience: One M&T Plaza is the home of M&T Bank. The 21-story New Formalist office tower was designed my Minoru Yamasaki, best known for designing the original World Trade Center twin towers in NYC and was completed in 1967. The structural steel of the building was produced locally by Bethlehem Steel. The 19th Floor of M&T Plaza, open to the public today, was recently remodeled and redesigned to include a board room, decision making room, an executive kitchen and spacious dining rooms. The view of the city of Buffalo from the floor is spectacular.
