  • Location originally occupied by Browns Building
  • 1850 - Marine Bank opens at 79 Main Street
  • 1880 - Marine Bank moves to 220 Main Street
  • 1915 - Marine National Bank building is designed by E.B. Green
  • 1972 - Marine Midland bank moved across the street to the Marine Midland Center, now HSBC Tower, which required the demolition of multiple buildings and now blocks vehicles and view down Main Street.
  • 1973 - The bank put 233 Main Street and 241 Main Street up for sale together for $5 million.
  • 1976 - The bank sold the two mostly empty buildings for $2.2 million as part of a larger deal involving an office tower on Park Avenue in Manhattan.
    • The buyer was more interested in the Manhattan building, and sold the two Buffalo buildings to investors from the Bronx for a much lower price. The assessment and taxes were much higher than the investors expected, so they sold the buildings to long-time owner David Sweet for $500,000.
    • Then Marine Midland ran out of room in the tower and leased a floor in its old building at 233 Main Street , followed by more floors in that building and also in 241 Main Street . Sweet then bought the old bookstore building at 251 Main Street , and the bank leased the entire structure. courtesy The Buffalo News
