The Limerick National Bank was located on Main Street in Limerick. The bank is known for its idea for creating a savings department and being the first bank to create such a department.

The bank's first president, Jeremiah M. Mason, conceived of the idea that it would be possible, and of mutual interest to the bank and its patrons, if the bank paid patrons a fixed percent of money each quarter on the balance of each account that the patron had held with the bank.
