The
Regia was a two-part structure in
Ancient Rome lying along the
Sacra Via at the edge of the
Roman Forum that originally served as the residence or one of the main headquarters of
kings of Rome and later as the office of the
Pontifex Maximus, the high priest of Roman state religion. It occupied a triangular patch of terrain between the
Temple of Vesta, the Temple of
Divus Julius and Temple of
Antoninus and
Faustina. Only the foundations of Republican/Imperial Regia remain. Like the Curia it was destroyed and rebuilt several times, as far back as the Roman monarchy. Studies have found multiple layers of similar buildings with more regular features, prompting the theory that this "Republican Regia" was to have a different use.
