Completed in 1975, Pennzoil Place consists of two 36-story trapezoidal towers of dark bronze-tinted glass connected by a 115-foot-high, glass-enclosed courtyard. Pennzoil Place was dubbed the Building of the Decade in 1975 by famed New York Times architecture critic Ada Louise Huxtable due to its dramatic sculptural silhouette. The building is also considered significant in architectural circles for breaking the modernist glass box made popular by followers of Ludwig Mies van der Rohe and for introducing the era of postmodernism.
