The Baekje Historic Areas (Korean: 백제역사유적지구) is a UNESCO World Heritage Site that consists of eight monuments in three cities in South Korea: Gongju, Buyeo, and Iksan.

The Baekje Historic Areas were inscribed as a UNESCO World Heritage Site on 8 July 2015 at the 39th session of the Committee.

Baekje had been founded on a small area on the banks of the Han River, which is the present-day Seoul (Hanseong), in 18 BC,[2]: 79–81  with population migrating from Goguryeo, and over the years the city was enlarged toward the southwestern part of the country.

This relocation facilitated the fledgling state of Baekje to imbibe from Chinese culture and architecture related to city planning, and it also subscribed to Buddhism.

In the 6th century, Gyeomik, a Buddhist monk of Baekje, went to India to learn more about Buddhism and bring back the scriptures, which were translated to the local language.

Buddhist philosophy spread widely among all sectors of the society, and the ruler considered himself as Buddha to exercise royal control over his subjects.

This also enabled a close interaction with China and Japan, not only in the field of religion and philosophy but also in building temples in these countries during the 5th to 7th centuries.

This period also witnessed the emergence of East Asia as a "geo-cultural circle" with a uniform writing pattern with Chinese characters, practice of Buddhism, and adoption of Confucian legal codes.

[2]: 79–81  The city prospered for nearly 700 years from 18 BC to 660 AD with its neighbouring kingdoms of Goguryeo to the north and Silla to the east.

[1] A special organization called the Baekje Historic Areas Conservation and Management Foundation has been set up with all stakeholders on board; central, provincial, and local governments and community associations are involved.

It was built as a defense fortification adapted to the local topography by linking mountain peaks and bridging the valleys.

It is located on top of a small hill (elevation 75 metres (246 ft)) on the southern side of the Geumgang River.

It is situated on the Busosan Mountain (elevation 106 metres (348 ft)) located on the northern extremity of Buyeo, on the west bank of the Geumgang River.

Built during the Sabi period, the temple has engravings on the pagoda that memorialize the Tang dynasty's victory over Baekje.

The temple has a layout of a central gate, prayer and lecture halls, and the monks' residential area, all linked by passages.

Excavations revealed the main gate on the eastern part of Buyeo, next to the Royal Tombs in Neungsan-ri, which was of 9.5 metres (31 ft) width built with rectangular stones.
