Tama-udun Royal Mausoleum is a grave for the line of kings of the Second Sho Dynasty, with three burial chambers whose use is depicted by an epitaph that states: the central chamber is for the King and Queen before their bones are washed, the east chamber is their final resting place, and the west chamber is for other members of the Royal family. At the site, there is also a museum near the entrance and ticketing area. Prior to the Battle of Okinawa, guards were stationed around the tomb, as they had been during the Ryukyu Kingdom era. It became a World Heritage Site in the year 2000.
