Holwell is a small village and a civil parish two miles north of Hitchin in Hertfordshire, England, near the Bedfordshire border. The parish was historically part of Bedfordshire, being transferred to Hertfordshire on 30 September 1897. At the 2011 Census the population of the village was 361. The church is unusual and, although largely rebuilt, retains some Perpendicular features and an interesting brass to Richard Wodehouse.
