Xi'an rewards visitors who prioritize wisely, since its highlights span over two thousand years of history within easy reach of each other. The Terracotta Army, part of the Mausoleum of Qin Shi Huang and housed in the Terracotta Army Museum, remains the citys defining sight, with thousands of life-size warriors still guarding an emperors tomb. Back in the center, the intact City Wall of Xian offers a rare chance to bike atop a complete Ming-dynasty fortification, while the Big Goose Pagoda anchors the citys Buddhist heritage. Rounding things out, the Muslim Quarter delivers centuries of Silk Road culture through its food stalls and mosques, making these picks the fastest route to understanding Xian.
