  A number of errors in Marco Polo's account have been noted: for example, he described the bridge later known as Marco Polo Bridge as having twenty-four arches instead of eleven or thirteen. He also said that city wall of Khanbaliq had twelve gates when it had only eleven. Archaeologists have also pointed out that Polo may have mixed up the details from the two attempted invasions of Japan by Kublai Khan in 1274 and 1281. Polo wrote of five- masted ships, when archaeological excavations found that the ships had only three masts.
