On November 3, 1992 the Seiden (Main Hall), heavily bombarded and turned into ashes by U.S. armed forces during the war, was restored along with the Nanden (South Hall) and the Hokuden (North Hall) in commemoration of the reversion's 20-year anniversary. With a 500-year history and having burned down four times, today's Shuri Castle is a replica of the castle restored in 1712 and designated a national treasure in 1925.
