Set of underground galleries at Sakkara serving as the burial place of the sacred Apis bulls from the Eighteenth Dynasty onwards. The term Serapeum strictly refers only to the Graeco-Roman temple at ground level, dedicated to the god Serapis.
This term was applied to two places. The first is at Saqqara; and it refers to the underground galleries which contained the burial chambers of the Apis bulls. The second place is at Alexandria where there has been a temple from Greco-Roman times dedicated to the cult of the god Serapis or the Apis Bull in those times.
