below it. In 1908, Shuri City bought the castle from the Japanese government; however, it did not have funding to renovate it. In 1923, thanks to Japanese architect Ito Chuta, Seiden survived demolition after being re-designated a prefectural Shinto shrine known as Okinawa Shrine. In 1925, it was designated as a national treasure. Despite its decline, historian George H. Kerr described the castle as "one of the most magnificent castle sites to be found anywhere in the world, for it commands the countryside below for miles around and looks toward distant sea horizons on every side." World War II During World War II, the Imperial Japanese Army had set up its headquarters in the castle underground, and by early 1945 had established complex lines of defense and communications in the regions around Shuri, and across the southern part of the island as a whole. The Japanese defenses, centered on Shuri Castle, held off the massive American assault from 1 April through the month of May 1945. Beginning on 25 May, and as the final part of the Okinawa campaign, the American battleship Mississippi shelled it for three days and by 27 May it was ablaze. The Japanese retreated during the night, abandoning Shuri, while the US forces continued to pursue them south. US Marine and Army units secured the castle against little resistance. On 29 May, Maj. Gen. Pedro del Valle—commanding the 1st Marine Division—ordered Captain Julian D Dusenbury of Company A, 1st Battalion, 5th Marines to capture the castle, which represented both strategic and psychological blows for the Japanese and was a milestone in the campaign. Post-war After the war, the University of the Ryukyus was established in 1950 on the castle site, where it remained until 1975. In 1958, Shureimon was reconstructed and, starting from 1992, the 20th anniversary of reversion, the main buildings and surrounding walls of the central castle were reconstructed. At present, the entire area around the castle has been established as "Shuri Castle Park". In 2000, along with other gusuku and related sites, it was designated as a UNESCO World Heritage Site. However, only remnants such as stone walls and building foundations extant before 1950 are officially designated as World Heritage. In addition, 2000 saw the Shureimon gate at Shuri Castle featured on the new 2000 yen note, which entered circulation to commemorate the new millennium and the 26th G8 summit, which was held
