My family and I visited the Mausoleum - the year that they were accorded the UNESCO World Heritage site. to celebrate they achievement, visitors were given free entry into the site.There is a lot to see at the museum itself before heading out to catch a bus ride to see the tombs. This site is able to provide you the full knowledge of the Xixia Dynasty before it was totally destroyed by Genghis Khan and his army in 1227.
