Between 111 and 114, Trajan built the Via Traiana Nova, running from the Syrian border to the Red Sea through Petra. This road followed the old routes of Nabataean caravans. In the shadow of the Pax Romana, this route revived trade between Arabia, Syria, and Mediterranean harbors. In 125 AD, one of Emperor Hadrian's administrators left marks in Petra, pointed out by documents found at the Dead Sea. In 130 AD, Hadrian visited the former Nabataean capital, giving it the name of Hadriane Petra Metropolis, imprinted on his coins. His visit, however, did not lead to any boom in architectural development and new buildings as it did in Jerash. The province's governor, Sextius Florentinus, erected a monumental mausoleum for his son near the end of the al-Hubta (King's Wall) tombs, which had been generally reserved during the Nabataean period for the royal family.
