Lǐquán
Liquan lies north of the Wei River, amid the hills overlooking the Guanzhong plain. Mount Jiuzong in the district holds Zhaoling, the tomb of the Tang emperor Taizong and his empress Zhangsun. Construction began with the empress's burial in 636, and the emperor joined her there in 649. The mausoleum used the mountain itself as its burial mound, setting a precedent for later Tang imperial tombs. Numerous ministers and members of the imperial family were buried around it, forming an extensive funerary landscape.
