The My Son compound
This is, for me, the singe most interesting item I’ve seen during this trip. Built during 1000 years (from 4th to 14th centuries) by the Champas kings as a burial and worship place, the site was largely destroyed by US air raids in the ’60s.
Fortunately, enough was left so we can see something and imagine the rest. Note: the heads of the statues are replicas. The originals are at the Louvre in Paris, removed during the colonial times.
