One Financial Plaza is a 374 ft (114 m), 28-story building in downtown Fort Lauderdale, Florida was opened in 1972. At the time of its opening, it was the tallest building in the Fort Lauderdale area. It has since been surpassed by several buildings. Currently, it is the city's fourth tallest building. One Financial Plaza bears a striking resemblance to the Chase Tower in Amarillo, Texas. They were built around the same time (Chase Tower opened in 1971, the year before One Financial Plaza opened), and Chase Tower is only a few floors taller, at 31 stories.
When the building was constructed in 1972, it was known as the Landmark Bank Building, after its builder and main tenant, Landmark Bank. Landmark Bank was acquired by C&S in 1985, and after a series of mergers and acquisitions, became a part of Bank of America. In 2002, Bank of America moved into a nearby building, and Union Planters Bank moved into the building the following year. The name on the building was changed to "Union Planters", and later to "Regions" when Regions Bank merged with Union Planters in 2004.
