The Zhang Qian Memorial Hall in Chenggu County, about thirty kilometres east of central Hanzhong, honours the diplomat and explorer whose second-century BC journeys to Central Asia established the trade routes that connected China to Rome. The site includes a landscaped memorial park, a statue of Zhang Qian, and a museum covering his journeys and the subsequent development of Silk Road trade. It is less visited than the Wuhou Temple complex but has a quieter, more contemplative atmosphere.
Zhang Qian made two major expeditions west: the first from 139 to 126 BC, and a second from 119 to 115 BC. He brought back knowledge of places unknown to the Han court — Ferghana (with its famous heavenly horses), Bactria, Sogdia, Parthia — and his reports directly influenced Han military and commercial strategy. The Silk Road as a functioning trade system emerged within decades of his return, making him one of the more consequential explorers in world history despite remaining largely unknown outside China.
