Khorat Museum, Nakhon Ratchasima

Although small, the Khorat Museum systematically deals with each of the times period from the Iron Age, Dvaravati, Khmer, Ayutthaya and Ratanakosin periods. Plenty of information is available for each of these periods based on finds and archaeological digs. The one drawback is the lack of information in English but an official is availabale to answer questions.
