The Serapeum of Saqqara was the ancient Egyptian burial place for sacred bulls of the Apis cult at Memphis. It was believed that the bulls were incarnations of the god Ptah, which would become immortal after death as Osiris-Apis. a name which evolved to Serapis (Σέραπις) in the Hellenistic period, and Userhapi (ⲟⲩⲥⲉⲣϩⲁⲡⲓ) in Coptic. It is part of the Saqqara necropolis, which includes several other animal catacombs, notably the burial vaults of the mother cows of the Apis.[1]

Over a timespan of approximately 1400 years, from the New Kingdom of Egypt to the end of the Ptolemaic Period, at least sixty Apis are attested to have been interred at the Serapeum. For the earliest burials, isolated tombs were constructed. As the cult gained importance, underground galleries were dug that connected subsequent burial chambers. Above ground, the main temple enclosure was supplemented by shrines, workshops, housing and administrative quarters.[2]

The Serapeum was closed in the beginning of the Roman period, after 30 BC. In the subsequent centuries large-scale looting took place. Many of the superstructures were dismantled, the burial vaults broken into, and most of the mummified Apis and their opulent burial goods removed.

In 1850 Auguste Mariette rediscovered the Serapeum, and excavated it the following years. He found two undisturbed Apis burials, as well as thousands of objects related to centuries of cult activity. These included commemorative stela with dates relating to the life and death of the Apis and the construction of their burial vaults. This data was crucial for the establishment of an Egyptian chronology in the 19th century.

The Greater Vaults of the Serapeum, known for the large sarcophagi for the mummified bulls, are accessible to visitors.
