The present Chuguji Temple is located on the east side of the Horyuji eastern precinct,
but it was originally located about 400 meters east of it. To distinguish it from the present Chuguji Temple, it is called “Chuguji Temple Ruins”. The excavation confirmed that the main hall and the pagoda were built in a straight line, which is called “Shitennoji-style arrangement” that is the same arrangement as the Ikarugadera Temple (Wakakusa Garan) built by Prince Shotoku. However, it seems to be an incomplete temple because no lecture hall and chorister were found. It was designated as a National Historic Site in 1990 and 2001.
