Shōryūji Castle is classified as a flatland castle (its layout: Teikakushiki), and is located in Kyōto. During the pre-modern age, it found itself within the borders of Yamashiro Province. It is associated with the Hosokawa clan. Dates in use: 1339 - 1649.

This castle was established in 1339 by Hosokawa Yoriharu, a samurai loyal to the first of the Ashikaga shoguns & served as a strategically important castle in the defence of Kyoto. Much later, in 1578, the castle would become the residence of Gracia, wife of Hosokawa Tadaoki & daughter of the infamous Akechi Mitsuhide.

This rather compact, historical site appears to have erupted out of the ground in the middle of suburban Kyōto. There's a rebuilt corner turret & two gates that appear to have been rebuilt using traditional methods. There is one other building, an exhibition hall which contains artifacts & information relating to the site.
