Nijo Castle was built in 1601-1626 as the Kyoto residence of the Tokugawa shoguns and is now a UNESCO World Heritage Site, one of the seventeen Historic Monuments of Ancient Kyoto. Its Ninomaru Palace is famous for "nightingale floors" that chirp underfoot, a side effect of the clamp-and-nail flooring rather than a deliberate security feature. Visitors can also walk the stone-walled moats and the Ninomaru and Honmaru gardens. The site holds a 4.0/5 rating from 3,195 votes.
Commissioned by Tokugawa Ieyasu in 1601 and completed in 1626, Nijo Castle served as the Kyoto base of the Tokugawa shogunate and was the site where shogunal rule was formally returned to the Emperor in 1867. The complex spans 275,000 square metres with two concentric moated fortifications, the National Treasure-listed Ninomaru Palace, the ruined Honmaru Palace, and several gardens including the Ninomaru Garden designed by Kobori Enshu. Ninomaru Palace's corridors have "nightingale floors" that produce a chirping sound as visitors walk across them. Donated to Kyoto city in 1939, the castle opened to the public in 1940 and remains open today.
