First National Bank of St. Paul was formed in 1864. In 1931, after acquiring Merchants Bank in the East Tower, the financial company built the adjacent West Tower. At 417 feet, the Art Deco high-rise was St. Paul’s tallest until 1986. More importantly, in 1936, the bank affixed a 50 foot, 1st neon sign onto a 100 foot steel tower. The bank’s name has long since disappeared in a series of mergers resulting in U. S. Bank. But the iconic sign continues to brighten the evening sky over downtown St. Paul. In 2017, it was announced part of the First National Bank Building was being converted from offices into apartments.
