Described by the famous Venetian traveller Marco Polo in his book, the Lugou Bridge, as it is known in China, became internationally known by the adventurer's name. Written 20 years after his visit to Cathay, in The Travels of Marco Polo, the explorer described the bridge as a wonder of the orient, although his faulty memory played some tricks on him.
When you leave the City of Cambaluc and have ridden ten miles, you come to a very large river which is called PULISANGHIN, and flows into the ocean, so that merchants with their merchandise ascend it from the sea. Over this River there is a very fine stone bridge, so fine indeed, that it has very few equals. The fashion of it is this: it is 300 paces in length, and it must have a good eight paces of width, for ten mounted men can ride across it abreast. It has 24 arches and as many water-mills, and 'tis all of very fine marble, well built and firmly founded. Along the top of the bridge there is on either side a parapet of marble slabs and columns, made in this way. At the beginning of the bridge there is a marble column, and under it a marble lion, so that the column stands upon the lion's loins, whilst on the top of the column there is a second marble lion, both being of great size and beautifully executed sculpture. At the distance of a pace from this column there is another precisely the same, also with its two lions, and the space between them is closed with slabs of grey marble to prevent people from falling over into the water. And thus the columns run from space to space along either side of the bridge, so that altogether it is a beautiful object.
