the 1st century BCE to celebrate his father's victory over Jugurtha. The complex, of which only parts of the foundations remain, was originally terraced; during the Flavian dynasty, it underwent major renovations, and the cult of Serapis was associated to that of Isis. The temple was finally demolished during the 6th century. Campus Martius This temple, dedicated to Isis and Serapis, was first dedicated by the triumvirs in 43 BCE in Rome. However, due to later tensions between Octavian (later Augustus Caesar) and Marc Antony, the temple was not built. Following the Battle at Actium, Augustus banned the religion from within the pomerium of Rome altogether. The temple was finally built by Gaius Caligula on the area known as Campus Martius, between the Saepta Julia and the temple of Minerva c. 37–41 CE. The Serapeum, long and wide, was divided in three sections: a rectangular area could be accessed first by walking under monumental arches; an open square, adorned with red granite obelisks brought to the city during the 1st century and erected in couples, followed. The centre of the square was likely occupied by the temple dedicated to Isis, while the third section, a semicircular exedra with an apse presumably hosted the altar dedicated to Serapis. Fragments of the obelisks, some quite large, have been found around the current church of Santa Maria sopra Minerva; some archaeologists have proposed that the obelisk facing the Pantheon (see picture) may have been repositioned from the temple to its current location. The building was destroyed in the great fire of the year 80 CE and rebuilt by Domitian; further renovation was initiated by Hadrian, while Septimius Severus ordered the necessary upkeep of the temple's structure. Written records attest to the Serapeum's existence and ritual activity until the 5th century. Quirinal Hill The temple built on Quirinal Hill and dedicated to Serapis was, by most surviving accounts, the most sumptuous and architectonically ambitious of those built on the hill; its remains are still visible between Palazzo Colonna and the Pontifical Gregorian University. The sanctuary, which lay between today's piazza della Pilotta and the large square facing Quirinal Palace, was built by Caracalla on the western slopes of the hill, covering over , as its sides measured . It was composed by a long courtyard (surrounded by a colonnade) and by the ritual area, where statues and obelisks had been erected. Designed to impress
