익산 왕궁리 유적

A UNESCO-listed Baekje royal palace site in Iksan where excavated buildings, workshops, gardens and toilets reveal how a seventh-century court actually functioned

On the program

Baekje palace archaeology, ancient sanitation, royal craft production, palace gardens, UNESCO history, architectural planning and the later Buddhist temple phase

The setting

A broad outdoor archaeological field with palace-wall traces, building foundations, a rear garden, workshop and toilet zones, the five-story stone pagoda and an interpretation museum beside the ruins

KORInform take

Wanggung-ri is unusually rewarding because palace archaeology here reaches beyond ceremonial architecture into plumbing, craft production and service spaces—the systems that kept royal life running

A palace with plumbing

The most memorable ruin at Wanggung-ri may be a toilet. Archaeologists identified three large latrines inside the Baekje palace, including one trench more than ten metres long. Parasite eggs in the soil confirmed what the architecture already suggested: this was a working sanitation system

The largest toilet measured about 10.8 metres by 1.8 metres and more than three metres deep. A sewage channel connected the facility to drainage outside the palace area, while smaller internal blocks suggest that several people could use the trench at once. Excavated wooden sticks appear to have served for cleaning

That detail changes the scale of the site. Wanggung-ri was not only a ceremonial compound for a king; it was a populated palace with water management, waste disposal and staff using shared infrastructure every day

Gold and glass behind the audience halls

The palace was planned inside a rectangular enclosure about 240 metres wide and 490 metres long. Major ceremonial and political buildings occupied the southern half, while the higher northern ground contained a rear garden. The northwestern service zone held workshops and the toilets

Excavation of the workshop area produced crucibles, furnace material, whetstones and partially finished objects tied to gold, bronze and glass production. Gold wire, sheet, nails, ornaments and glass-working debris indicate that palace craftspeople were making and finishing luxury goods inside the enclosure rather than simply receiving them from elsewhere

The garden shows a different form of court infrastructure. Excavators found waterways, stones and landscaped features in the northern section, giving the palace separate spaces for state business, production, sanitation and retreat. UNESCO’s evaluation highlights Wanggung-ri as an unusually clear example of the rectangular planned palace layouts circulating across East Asia in the sixth and seventh centuries

When the palace became a temple

Wanggung-ri was built during the reign of King Mu, who ruled Baekje from 600 to 641, as part of the kingdom’s major development around Iksan. UNESCO treats the site together with Mireuksa as evidence for a secondary Sabi capital and for Baekje’s wider exchange with China and Japan

The palace did not keep the same function. Major buildings were later dismantled and the compound was converted into a Buddhist temple. That change explains the most conspicuous standing structure today: the Wanggung-ri Five-story Stone Pagoda, which belongs to a later religious phase rather than the original palace plan

During repairs in 1965, Buddhist reliquaries were found inside the pagoda, including objects spanning Baekje to Goryeo. The site therefore preserves several political and religious lives in the same ground: royal palace, workshop complex, temple and later pagoda landscape

Before you go

The site reads best with the exhibition hall first or last rather than as an isolated field of foundations. On the ground, the toilet and workshop zone gives the clearest sense of daily palace operation, while the central building traces and rear garden explain hierarchy and planning. The five-story pagoda belongs to the later temple layer
