Nijo Castle (二条城, Nijōjō) was built in 1603 as the Kyoto residence of Tokugawa Ieyasu, the first shogun of the Edo Period (1603-1867). His grandson Iemitsu completed the castle's palace buildings 23 years later and further expanded the castle by adding a five story castle keep.

After the Tokugawa Shogunate fell in 1867, Nijo Castle was used as an imperial palace for a while before being donated to the city and opened up to the public as a historic site. Its palace buildings are arguably the best surviving examples of castle palace architecture of Japan's feudal era, and the castle was designated a UNESCO world heritage site in 1994.
