The honden (本殿 main hall?), also called shinden (神殿?) or sometimes shōden (昇殿?), as in Ise Shrine's case, is the most sacred building at a Shinto shrine, intended purely for the use of the enshrined kami, usually symbolized by a mirror or sometimes by a statue. The building is normally in the rear of the shrine and closed to the general public. In front of it usually stands the haiden, or oratory. The haiden is often connected to the honden by a heiden, or hall of offerings.
Physically, the honden is the heart of the shrine complex, connected to the rest of the shrine but usually raised above it, and protected from public access by a fence called tamagaki. It usually is relatively small and with a gabled roof. Its doors are usually kept closed, except at religious festivals. Shinto priests themselves enter only to perform rituals. The rite of opening those doors is itself an important part of the shrine's life. Inside the honden is kept the go-shintai (御神体?), literally, "the sacred body of the kami". The go-shintai is actually not divine, but just a temporary repository of the enshrined kami.
