Sardis was the capital of the Lydians, a powerful Iron Age civilization (8th-6th centuries BCE) known for its wealth and early coinage production. The city had a unique urban structure with fortified walls, terraces, and distinct zones, including settlements, sanctuaries, and cemeteries. The cemetery of Bin Tepe features some of the largest tumulus tombs in the world. The Lydians developed a distinct language and religious system and were widely mentioned in Greek, Roman, and European texts. After their fall, Sardis remained significant under Persian, Greek, Roman, and Byzantine rule.

Brief synthesis Sardis was one of the pre-eminent Iron Age cities of the ancient world. Located in western Türkiye, it was the capital and only city of the Lydians. The Lydians rose to prominence in the 8th-6th centuries BCE, conquering most of western Anatolia and establishing the first empire in the region during the Iron Age. They invented coinage, an innovation that was quickly adopted by their neighbours, with long and widespread impacts on global economies.

They protected the city with a regionally distinctive twenty-meter-thick fortification wall. The necropolis of Bin Tepe is located seven to seventeen kilometres north of the citadel of Sardis, which includes more than 119 tumuli. The three large tumuli at Bin Tepe are amongst the largest tumulus tombs in the world, and amongst the first to include features such as the crepis wall and marker stones. Criterion (iii): Sardis and the Lydian Tumuli of Bin Tepe testify to the Lydian civilisation, a native Anatolian people in western Asia Minor during the 1st millennium BCE. The property bears testimony to a vanished culture that had a profound impact on the history of the ancient world though its architecture, customs, and cultural practices. The Lydians had their own language and worshipped a unique pantheon of gods. The city of Sardis had a distinctive urban plan and…
