 One of the canals connects Óc Eo to the town's seaport while another goes north-northeast to Angkor Borei.Óc Eo is longitudinally bisected by a canal, and there are four transverse canals along which pile-supported houses were perhaps ranged.Archaeological sites reflecting the material culture of Óc Eo are spread throughout southern Vietnam, but are most heavily concentrated in the area of the Mekong Delta to the south and west of Ho Chi Minh City.
