Great Wymondley is a village and ancient parish in North Hertfordshire. The parish was merged in 1937 with the neighbouring parish of Little Wymondley to become the civil parish of Wymondley.
Great Wymondley is a village situated near Hitchin in Hertfordshire. It is dominated by its small Norman church with a large apsidal chancel and 15th century nave roof. There are also earthworks of a former motte-and-bailey castle, and Delamere House, an elegant Elizabethan building. There are also a number of thatched cottages, including a row of terraced cottages each named after one of King Henry VIII's wives. Despite the names, Great Wymondley is much smaller than its neighbour, Little Wymondley.
