Seleucia on Tigris — A settlement in Babylonia
Seleucia was a major Mesopotamian city of the Seleucid, Parthian, and Sasanian empires. It stood on the west bank of the Tigris River opposite Ctesiphon.

It was named for Seleucus I Nicator, who enlarged an earlier settlement and made it the capital of his empire around 305 bc. It was the largest and most important of the many cities to bear its name.

In 117 AD, Seleucia was burned down by the Roman emperor Trajan during his conquest of Mesopotamia, but the following year it was ceded back to the Parthians by Trajan's successor, Hadrian, then rebuilt in the Parthian style. It was completely destroyed by the Roman general Avidius Cassius in 165. Sixty years later, it was rebuilt by Persian emperor Ardashir I.

The city eventually faded into obscurity and was swallowed by the desert sands, probably abandoned after the Tigris shifted its course.

Modern location: Ruins
