The archaeological site extends considerably beyond the theatre, covering the remains of the Roman city from the 1st through 4th centuries AD. The central area includes the forum — the civic heart of any Roman city — flanked by the remains of temples and public buildings. The Capitoline Temple, dedicated to the Roman state triad of Jupiter, Juno, and Minerva, survives with several columns standing. A temple to Isis and one to Liber Pater reflect the religious diversity of Sabratha's population, which mixed Punic, Berber, and Roman traditions.
The baths are extensive and some of the mosaic floors have survived, though the finest mosaics from the site have been removed to the Sabratha Museum for protection. Walking through the site, the Punic period is visible beneath the Roman layers in some areas — Sabratha's Phoenician and Numidian past predates its Roman prosperity by several centuries. The site, along with Leptis Magna and the Cyrene complex, was inscribed as a UNESCO World Heritage Site in 1982. A site museum adjacent to the ruins displays sculpture, mosaics, and smaller finds from the excavations.
