Marble Boat is also called Han Chuan (Land Boat), or Bu Ji Zhou (Unmoored Boat), because it is not navigable. In ancient China, people often built it as a part of decoration in classical gardens. It is a boat-shaped architecture built in the middle of water or port near the bank. In parks, marble boat can enrich the beautiful scenery, as well as provide a seat for people to enjoy the sight and feast.   

Also known as "Qingyanfang" (Boat of Clearness and Comfort), the Marble Boat is positioned at the west bank at the foot of Longevity Hill.

The Marble Boat was built in 1755 in Chinese style, imitating the sailing boats which Qianlong (1711-1799) took during his inspection to Southern China. As an old saying goes, "water can carry the boat as well as overturn it," meaning that water symbolizing the common people can uphold the royal boat, or it can swamp the boat. Emperor Qianlong had the huge Marble Boat fastened in the water to indicate the steadfast rule of the Qing Dynasty (1644-1911).

In 1860, it was burned down, and then rebuilt in Western style in 1893 through Empress Dowager Cixi's embezzling naval funds. Inlaid with colorful glass windows and wheels and paved with colored bricks, the boat is 36 meters (118.1 feet) long, two stories high. Using the huge mirrors fixed on each deck, on rainy days Cixi could enjoy the dainty lake scene while having tea. Four dragon heads mounted in each direction serve as drains, allowing rain water to be channeled picturesquely out of their mouths.

From nearby, it gives off an air of royal vigor. Seen from afar, the big boat looks very much like a ship ready for sailing. A thick layer of moss covering the outside of the boat reveals a sense of historical vicissitude. Today, Marble Boat has become a notable sight in Summer Palace.
