Fifty kilometers northwest from Beijing lies the Ming Tombs – the general name given to the mausoleums of 13 emperors of the Ming Dynasty (1368 – 1644). The mausoleums have been perfectly preserved, as has the necropolis of each of the many emperors. Because of its long history, palatial and integrated architecture, the site has a high cultural and historic value. The layout and arrangement of all thirteen mausoleums are very similar but vary in size as well as in the complexity of their structures.
