The unique part of Po Klong Garai tower lies in the clay bricks used for building it and the glue used to stick those bricks together. The glue is believed to have been made from an extract from a plant species called Dipterocarpus alatus, a tropical forest tree common in Thailand, Cambodia, Laos and Vietnam. How the Dipterocarpus alatus extract was mixed with other materials to make the glue remains a mystery.
