The inscriptions that the visitor can see in the temples are those carved on the door jambs of the entrances to the sanctuaries. Inscriptions were also carved on steles, but the majority of these are now housed in the Conservancy at Angkor to prevent them from being stolen. More than 1,200 inscriptions have been discovered, but it is likely that more has disappeared, or have not yet been found. The script evolved over the centuries up to the Angkorian period.
