Furusutobaru Castle

About

Furusutobaru Castle (Furusutobaru jō) are the ruins of stone ramparts that were thought to have been a Ryukyuan gusuku fortification, but are now thought to have been a residence site, as many household items have been excavated but no weapons have been found. Located in the city of Ishigaki, Okinawa, it was designated a National Historic Sites in 1978.
