Archaeologists found a structure in in Gyeongju, South Korea, which appears to be the remains of a flush toilet made during the Unified Silla Dynasty in the 8th century.
The structure was found during excavations at a site North-East of the Dong Palace in Gyeongju, the capital of the ancient kingdom of Silla (57 BC-935 AD) which ruled about two-thirds of the Korean Peninsula between the 7th and 9th centuries. The structure has a form resembling a stone flush toilet and draining system inside. According to the archaeologists the oval-shaped flush toilet, made out of granite, has a drain and two rectangular slab stones on both sides apparently for users to plant their feet on when they are squatting. An official of the Gyeongju National Research Institute of Cultural Heritage stated it appears that human excrement was flushed down the drain by pouring water into the toilet given that the bathroom had no water inflow equipment.
