"The Beauregard-Keyes House stands out in a neighborhood—the French Quarter—already filled with standout buildings. Built in 1826, it’s a superb example of the then-newly-popular Greek Revival style, with its bossy pediment and sweeping granite stairs, which displaced the more austere Creole style. It’s been home to an illustrious roster of residents, including legendary 19th-century chess player Paul Morphy (born here in 1837 and world champion before he turned 20) and Confederate General P.G.T. Beauregard after the Civil War. Next door and visible even if you don’t take the guided tour is a small, walled parterre garden, restored to the formal style of the middle 19th century."
