Sardis (/ˈsɑːrdɪs/) or Sardes (/ˈsɑːrdiːz/; Lydian: Sfard; Ancient Greek: Σάρδεις Sardeis; Old Persian: Sparda) was an ancient city at the location of modern Sart (Sartmahmut before 19 October 2005) in Turkey's Manisa Province. Sardis was the capital of the ancient kingdom of Lydia, one of the important cities of the Persian Empire, the seat of a proconsul under the Roman Empire, and the metropolis of the province Lydia in later Roman and Byzantine times. As one of the Seven churches of Asia, it was addressed by John, the author of the Book of Revelation in the Holy Bible, in terms which seem to imply that its population was notoriously soft and fainthearted. Its importance was due first to its military strength, secondly to its situation on an important highway leading from the interior to the Aegean coast, and thirdly to its commanding the wide and fertile plain of the Hermus.
Sardis was situated in the middle of Hermus valley, at the foot of Mount Tmolus, a steep and lofty spur which formed the citadel. It was about 4 kilometres (2.5 mi) south of the Hermus. Today, the site is located by the present day village of Sart, near Salihli in the Manisa province of Turkey, close to the Ankara - İzmir highway (approximately 72 kilometres (45 mi) from İzmir). The part of remains including the bath-gymnasium complex, synagogue and Byzantine shops is open to visitors year-round.
Sardis was the capital of the ancient kingdom of Lydia, in present-day Turkey.
