Siheung Oido Museum

Siheung Oido Museum is a public museum on Oido Island in Siheung, Gyeonggi-do, dedicated to the archaeology and traditional culture of the Oido area — one of Korea's more archaeologically significant Neolithic sites on the West Sea coast. The museum's core exhibits cover the Neolithic Oido shell-mound archaeological site (about 5,000-year-old shell-mound and dwelling-site material excavated on the island in the 1990s), the specific coastal-fishing settlement pattern of Neolithic Oido, and the broader continuity of coastal-life culture from prehistory through the modern era. The museum sits within easy walking distance of the actual Oido shell-mound excavation site (protected as a public archaeological park with interpretive walking trails), which makes the visit an unusually integrated museum + on-site archaeology combination. Bilingual Korean/English interpretation. Free entry. Allow about 90 minutes for museum + site. Access: about 15 minutes from Oido Station (Suin-Bundang Line, Exit 1) by taxi or local bus. Pair with the broader Siheung West Sea coastal cluster including Siheung Gaetgol Eco Park (batch 2 verified), the Oido lighthouse and coastal walking paths, and Daebudo Island (batch 8 verified) for a full western-Seoul-metropolitan coastal day.
