The two buildings of the Amarillo National Bank, both by Dallas architects, dominate the Amarillo skyline and represent two generations of commercial design. The 1972 building is a sixteen-story reinforced concrete-frame structure, with its tower clad in a curtain wall of bronze glass, patterned by horizontal spandrels and projecting vertical mullions,

Miesian in inspiration. The slim tower rises from a low, New Formalist concrete- and travertine-clad pavilion. The 1983 building, also framed in reinforced concrete, is a twenty-four-story angular, reflective prism of blue glass, a breaking of the corporate box first ventured at Pennzoil Place in Houston (1976, Johnson/Burgee Architects).
