History
The history of Wellesley House School dates back to 1866 but the present main building was built in 1897 to 1898 in 6 acres (2.4 ha) of grounds. The school had been originally called Conyngham House and was located in Ramsgate. In 1929 Haddon Dene School was founded separately. Haddon Dene was initially a boarding and day school for girls, with boys accepted from 1933. During World War II, Haddon Dene expanded and taught older pupils, where as Wellesley House was temporarily evacuated to Rannoch in Scotland while the Broadstairs buildings were used by the British Army. In the 1950s Haddon Dene moved for expansion reasons to a town block away of the grounds of Wellesley House. In 1969 Wellesley House merged with St Peter's Court, another local prep school, whose grounds were then redeveloped. St Peter's Court had had two sons of King George V as pupils. The King felt corporal punishment of Prince George, Duke of Kent when he swam too far out to sea at Joss Bay, despite being warned not to, was appropriate. Wellesley House School itself taught one of the Dukes of Gloucester in the 1950s and other prominent pupils included Mike d'Abo, Chris Cowdrey and William Fox-Pitt. Wellesley's House first headmaster was C.H. Rose followed by C.R. Taylor. Another early headmaster was Leonard Moon. Originally a typical boys-only boarding prep school, girls were admitted in 1977. Haddon Dene school's first headmistress was Miss Olive Vyse who continued until 1968. Haddon Dene was without boarders at the time of the merger, and with smaller grounds.
On 22 September 2022, Haddon Dene School merged with Wellesley House School to form the newly named Wellesley Haddon Dene School. The Premises for the new school are as for Wellesley House School, at 114 Ramsgate Road, Broadstairs. It was planned that the merger could eventually lead to an expansion of pupil number to a maximum of 320 pupils.
The school has a number of pupils with Special educational needs and disability (SEND), which in 2023 stood at 23.
