Later on, many more Dvaravati sites were discovered throughout the Chao Phraya valley.

The two most important sites were Nakorn Pathom and Uthong ( in the present Suphanburi Province ).

The inscriptions of Dvaravati were in Sanskrit and Mon using the script derived from the Pallava script of the Pallava dynasty.

The religion of Dvaravati is thought to be Theravada through contacts with Sri Lanka, with the ruling class also participating in Hindu rites.

The Dvaravati art, including the Buddha sculptures and stupas, showed strong similarities to those of the Gupta dynasty.

The most prominent production of Dvaravati art are the Thammachakras or the Stone Wheels signifying Buddhist principles.

The eastern parts of the Chao Phraya valley were subjected to a more Khmer and Hindu influence as the inscriptions are found in Khmer and Sanskrit.
