Greenham Hall is a country house at Wellington in Somerset. It was once the home of Admiral of the Fleet Sir John Kelly. It is a Grade II listed building. Originally known as Tremlett House, the main building was constructed in 1848 for Thomas Edward Clarke, a solicitor. It was acquired by the Chapman family in 1880, by Admiral Sir John Kelly in 1920 and was then used as a collecting point for army units during the Second World War. It was bought by the Norman family shortly after the war and then by Henry Ayre in 1970. It is still owned by the Ayre family and became a hotel in 1985.
