Quarries and transportation routes of Angkor monument sandstone blocks

► We identified more than 50 sandstone quarries in the Angkor period. ► The quarry sites are distributed around a bank 2.4 km long at the southeastern foot of Mt. Kulen. ► A route of interconnected canals and rivers was identified that links quarry sites for the Angkor monuments to the Angkor area. ► A field investigation suggests that the canal was used for the transportation of sandstone blocks.
