About Temple of Janus#

The Temple of Janus is an ancient Roman shrine dedicated to the god Janus, traditionally situated within the civic heart of Rome. The monument is historically associated with a pair of doors whose open or closed state signalled whether Rome was at war or at peace.

The shrine dates back to Rome’s early religious traditions and was maintained and rebuilt at various times through the Republican and Imperial periods. Its symbolic role in Roman ritual and state religion is its principal significance to historians and visitors.

The temple and its remnants are located in the area of the Roman Forum, among Rome’s other central Republican and Imperial monuments.

  • Doors as war/peace symbol: Associated with the Roman practice of keeping the shrine’s doors open in wartime and closed in peacetime, a distinctive ritual symbol of Roman state religion.
