Ko Samui
The Bronze Drum of Dongson Culture (500–100 BCE) that was found on Ko Samui in 1977 is evidence that there were settlements of people on Ko Samui, Ko Pha-ngan, and their islets more than two thousand years ago. Some historians and archaeologists believe that the first group who migrated to Ko Pha-ngan were sea gypsies (Semung, and Proto-Malay) who travelled by boat from the Malay Peninsula.
