John Cleland
The Stormont Estate was established by the Reverend John Cleland (1755–1834) in the early nineteenth century. He built Stormont Castle in 1830 which was described as a "large plain house with very little planting about it". In 1858 the exterior of the castle was redesigned in the Scottish Baronial style by the local architect Thomas Turner. Some ancillary buildings were added at this time including a lean-to glasshouse and stables. A terraced garden and a walled kitchen garden were also created. When Cleland died in 1834 the estate went to John Cleland (1836–1893) and then finally to Arthur Charles Stewart Cleland (1865–1924).
