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.
Cirencester lies on the lower dip slopes of the Cotswold Hills, an outcrop of oolitic limestone. Natural drainage is into the River Churn, which flows roughly north to south through the eastern side of the town and joins the Thames near Cricklade a little to the south. The Thames itself rises just a few miles west of Cirencester.
