The Lonely Planet guidebook says......?
The town of Lopburi, 154km north of Bangkok, has been inhabited since at least the Dvaravati period (6th to 11th centuries AD) when it was called Lavo. Nearly all traces of Lavo culture were erased by Khmer and Thai inhabitants following the 10th century, but the Lopburi National Museum has many Dvaravati artifacts. Ruyins and statuary in Lopburi span a remarkable 12 centuries.
