Angkor Borei is an archaeological site located in the southern region of Cambodia, approximately 30 kilometers southeast of the town of Takeo. The site is known for its well-preserved ruins of an ancient city that dates back to the Funan period, which existed from the 1st to the 6th century AD.

The ancient city of Angkor Borei was a major center of trade and commerce in Southeast Asia during the Funan period. It was strategically located at the confluence of the Mekong and Bassac Rivers, which made it an important hub for maritime trade and communication with other parts of the region.

Today, the ruins of Angkor Borei include several well-preserved structures, including a rectangular-shaped city wall made of laterite blocks, a royal palace complex, and several temples and shrines. One of the most notable structures is a large brick temple known as Wat Phnom Da, which is located on top of a hill overlooking the Mekong River.

Visitors to Angkor Borei can explore the ruins on foot and marvel at the ancient architecture and engineering of the Funan period. The site also includes a small museum that showcases artifacts and relics from the site's excavation, including pottery, jewelry, and stone carvings.

Angkor Borei is located approximately 100 kilometers south of the city of Phnom Penh, and can be reached by car or bus. The site is open to visitors daily from 8:00am to 5:00pm, and admission fees apply.
