Dusit Tummakorn, head of the Phimai historical park in the northeastern province of Nakhon Ratchasima said that heavy rain caused flooding at many spots within the Phimai Khmer sanctuary, the main historic site in the province.
However, according to an initial survey, there has been no damage to the Khmer ruins from flooding, he said.
Ten pumps are operating to drain water from the site to prevent any damage to the bases of the stupas.
The historic site remains open for visitors, but there may be some inconvenience. The situation is expected to return to normal if there is no more rain today.
