In the 700-block of Louisiana downtown stand two buildings with a unique relationship to one another. Designed by Philip Johnson and John Burgee, Pennzoil Place (1976) is actually itself two identical trapezoidal towers separated by only a few feet, creating an interesting perspective on angles and a completely different appearance depending on where it’s viewed from. The newer Bank of America Center (originally RepublicBank Center 1983) is a Gothic-inspired tower with a defining triple-gabled roofline. The Johnson Burgee duo also designed this skyscraper, and did so in a way that accentuated the structure they had already executed across the street.
