Corinium was the Roman name for which English town?

Cirencester is a market town in east Gloucestershire, England, 93 miles (150 km) west northwest of London. Cirencester lies on the River Churn, a tributary of the River Thames, and is the largest town in the Cotswold District. It is the home of the Royal Agricultural University, the oldest agricultural college in the English-speaking world, founded in 1840.

The town's Corinium Museum is well known for its extensive Roman collection. The Roman name for the town was Corinium, which is thought to have been associated with the ancient British tribe of the Dobunni, having the same root word as the River Churn. The earliest known reference to the town was by Ptolemy in AD 150.

Even in Roman times, there was a thriving wool trade and industry, which contributed to the growth of Corinium. A large forum and basilica were built over the site of the fort, and archaeological evidence shows signs of further civic growth. There are many Roman remains in the surrounding area, including several Roman villas near the villages of Chedworth and Withington. When a wall was built around the Roman city in the late 2nd century, it enclosed 240 acres (1 km²), making Corinium the second-largest city by area in Britain.
