China's National Museum will now house a 2000-year-old royal garment made of more than 4000 pieces of jade sewn together with gold thread.
The royal armour - like garment was excavated from a tomb dating back to the Western Han Dynasty (206 BC - 25 AD).
The clothing is 1.74 meters long and is made up of 4248 pieces of jade held together by around 1.5 kg of gold thread.
Archaeologists believe a king of the State of Chu in the Western Han Dynasty wore it.
This is the oldest and most unique relic of its kind to be found in China.
The old building of the National Museum of China will go through renovation and enlargement from the year 2004 to 2007, expanding the floor space from 65000 at present to 150000.
