Kitanomaru Garden
Kitanomaru Garden was once part of Edo Castle and, later, a headquarters for the Imperial Guard until the end of World War II. It is now a haven for wildlife and the location of the Science Museum and Nippon Budokan, a 1964 Olympic venue that also hosted the Beatles in 1966. There are two Edo-period (1603–1867) gates within the park, including Tayasumon Gate, built in 1636. It is the oldest existing gate remaining from the castle and a designated Important Cultural Property. The garden was opened as a park in 1969 to commemorate the 60th birthday of the Showa Emperor (1901–1989).
