China: Capital Cities and Tombs of the Ancient Koguryo Kingdom

Last Monday I got a postcard from China.

It shows the Capital Cities and Tombs of the Ancient Koguryo Kingdom. Koguryo or Goguryeo was a Korean kingdom which at its peak of power controlled most of the Korean peninsula, large parts of Manchuria and parts of the Russian Far East and eastern Mongolia. It was one of the great powers in East Asia, until its defeat by a Silla-Tang alliance in 668. The Capital Cities and Tombs of the Ancient Koguryo Kingdom near the border of China and North Korea are since 2004 on the UNESCO World Heritage List.
