The sacrificial hall is actually a palace with three entries, with the inscriptions of "nationalism" "civil rights" and "people's livelihood" respectively on each entry. The hall's ceiling is tiled with a flag of the Republic of China, which Dr. Sun Yat-sen established in 1911. In the center of the hall sits the 4.6-meter-high marble statue of a sitting Dr. Sun Yat-sen. On the four sides of the statue there are relief sculptures reflecting Sun's glorious revolutionary life. The walls of the hall are decorated with the full text of "The Guidelines for Establishing a Nation" written by Dr. Sun and "The Premier's Will" compiled by Huhanmin, etc. Visitors will not only learn of Sun's efforts and achievements in overthrowing the feudal system, but also his ideology about the independence, prosperity and development of the country.

North to the sacrificial hall is the circular coffin chamber, the resting place of Sun's remains. They lie in a rectangular marble stone coffin capped with a reclining sculpture of Dr. Sun , which is the work of a Czechic sculptor. The coffin sits in a sunken circular pit with a diameter of 4 meters and a height of 5 meters so that visitors can gaze down on it as they circle around in silence.

Over the last three decades, Dr. Sun Yat-sen's Mausoleum has witnessed enormous changes. The whole mausoleum and its memorial buildings have been extensively renovated several times. Tourists to Nanjing usually visit the mausoleum and pay their respects to Sun Yat-sen, the great revolutionist. Endowed with rolling hills, a vast sea-like forest, many sights and rich resources, the mausoleum is majestic and magnificent. With the unique and successful design, the mausoleum has been dubbed "the First Mausoleum in the History of Modern Architecture ".
