Michuhol-gu, INCHEON Metropolitan city

This monument is a rock castle built on the top of Munhak Mt. in Incheon. It is called Michuhol Castle or Namsanseong. According to written documents (Dongsagangmok, Yeojidoseo), Munhak Mt. was the capital of king Michu (Biryu). It includes a rock castle site and a well called Biryujung. The castle, which contains inner and outer walls, was specially constructed to surround the mountaintop. Inside the castle, there was a beacon mound.

The 100m inner castle and 200m outer castle maximized the geological benefits in its construction. According to records, there was a 5m high wall at the center of the castle, however, most of the walls have been destroyed. The battle record at this site can be found in the Incheon Prefect Record.
