Located in Mingzuling Town, Xuyi County, 15 kilometers northwest of the county seat, it is the actual burial site of the grandfather of Zhu Yuanzhang, the founding emperor of the Ming Dynasty, and a clothes tomb for his great-grandfather and great-great-grandfather. Construction began in the 18th year of the Hongwu reign (1385 AD) and was completed in the 11th year of the Yongle reign (1413 AD), taking 28 years in total. It features a grand scale and magnificent momentum. In the 19th year of the Kangxi reign of the Qing Dynasty (1680 AD), the Yellow River diverted into the Huaihe River, submerging the mausoleum along with the ancient Sizhou City. It first emerged from the water during a spring drought in 1953, known locally as the "Great Mound." Reappearing in 1963, it was identified by Jiangsu archaeologists as the First Ming Mausoleum. Restoration began in 1976, and it opened to the public in 1982, designated as a Provincial Key Cultural Relic Protection Unit. In October 1996, it was approved as a Major Historical and Cultural Site Protected at the National Level. In 2008, it was officially rated as a National AAAA-Level Tourist Attraction.
