Ten years ago, at a spot known locally as "Black Rock", two men diving for sea cucumbers came across a large pile of sand and coral.
Digging a hole, they reached in and pulled out a barnacle-encrusted bowl. Then another. And another.
They had stumbled on the oldest, most important, marine archaeological discovery ever made in South East Asia, an Arab dhow - or ship - built of teak, coconut wood and hibiscus fibre, packed with a treasure that Indiana Jones could only dream of.
There were 63,000 pieces of gold, silver and ceramics from the fabled Tang dynasty, which flourished between the seventh and 10th centuries.
