The Italian Renaissance post office is clad in limestone, with a red tile roof and bracketed roof eaves. Elevated on a raised basement, the two-story height is masked by tall first-floor windows and low upper-floor windows that appear as an attic. A monumental stair leads to the tall, triple-arched loggia that is simpler than the fifteenth-century Brunelleschi Foundling Hospital model often used during Taylor’s tenure. The building was rehabilitated in 1982 as the Collin County Museum.
