Katsuren Castle is believed to be the oldest castle in Okinawa Prefecture and is a World Heritage Site. Katsuren Castle is a gusuku (Okinawa Prefecturen) style Japanese Castle. Katsuren Castle over looks Awase and Nakagusuku Bay on the Pacific Ocean, hence why Katsuren Castle was also referred to as Ocean Gusuku. Katsuren Castle was at the height of its power in the mid 15th century under Lord Amawari. Excavations of the site have lead to the discovery of precious tiles and Chinese porcelain which provide a further evidence of the wealth and stature of Katsuren Castle. Today only ruins remain including walls and some foundations.
