Leaving St. Paul’s gate (Porta San Paolo) along the Via Ostiense, stands the original Pyramid of Caius Cestius , a burial monument that this official who was in charge of the sacred banquets had erected as his own tomb between 18 and 12b.C. It is 37mt. high, built in imitation of the Egyptian pyramids, that were in fashion in Rome after the conquest of Egypt (30 to C.). It is built of a very firm composition of mortar and small stones faced with tablets of white marble. The original entrance was effected by means of an inclined shaft about halfway up the northern side of the Pyramid.
