Ilminster is a minster town and civil parish in the South Somerset district of Somerset, England, with a population of 5,808. Bypassed in 1988, the town now lies just east of the junction of the A303 (London to Exeter) and the A358 (Taunton to Chard and Axminster). The parish includes the hamlet of Sea.
Ilminster is mentioned in documents dating from 725 and in a Charter granted to Muchelney Abbey ( to the north) by Æthelred the Unready in 995. Ilminster is also mentioned in Domesday Book (1086) as Ileminstre meaning 'The church on the River Isle' from the Old English ysle and mynster. By this period Ilminster was a flourishing community and was granted the right to hold a weekly market, which it still does.
Ilminster was part of the hundred of Abdick and Bulstone.
In 1645 during the English Civil War Ilminster was the scene of a skirmish between parliamentary troops under Edward Massie and Royalist forces under Lord Goring who fought for control of the bridges prior to the Battle of Langport.
The town contains the buildings of a sixteenth-century grammar school, the Ilminster Meeting House, which acts as the town's art gallery and concert hall. There is also a Gospel Hall.
Note: From April 1st 2023 Somerset's five District Councils have become one as part of the County Council and accordingly South Somerset District Council has ceased as an entity. Somerset County Council is now called Somerset Council.
The parish council has responsibility for local issues, including setting an annual precept (local rate) to cover the council's operating costs and producing annual accounts for public scrutiny. The parish council evaluates local planning applications and works with the local police, district council officers, and neighbourhood watch groups on matters of crime, security, and traffic. The parish council's role also includes initiating projects for the maintenance and repair of parish facilities, as well as consulting with the district council on the maintenance, repair, and improvement of highways, drainage, footpaths, public transport, and street cleaning.
