Timgad, Trajan’s colony for Roman army veterans, was designed as a castrum; Leptis Magna, with Carthaginian roots, was developed first under Augustus. Leptis-born Septimius Severus renovated his hometown featuring a forum, basilica, and arch. Entrepreneurs, providing animals to Rome's amphitheaters, commissioned Hunting Baths with intimate vaulted spaces revealed on the outside and silhouetted against the sea, suggesting that they knew how to innovate and enjoy life.
