The school was founded
Arnold House Preparatory School around 1867 at 29 Parkgate Road in the city of
Chester, north England. The founders were Reverend James Clement Collier Pipon (also the first headmaster) together with Susan Augusta Griffiths, his wife. In 1874, Susan Griffiths died shortly after the birth of Philip James Griffiths Pipon, their only child. The following year, the school moved to the village of
Llanddulas on the coast of north Wales. The school was renamed
Arnold House School in 1875. It was an independent preparatory boarding school for boys, intended for the sons of army/navy officers, businessmen, clergy, gentry, and the middle classes in general. The school prepared pupils for the
Common Entrance examination aimed at entry to
public schools and also naval colleges. In the 1920s, pupil numbers increased and the school was divided into three boys' houses – Bingham's, Conwy's, and Pipon's – named after three alumni, all of whom became
Admirals in the
Royal Navy. The school closed around 1943 because of reducing numbers of pupils and
World War II. From that time, it became a Jewish
convalescent home. Later, school buildings were converted for residential use. The main building is known as
Llanddulas Hall. ==Alumni==
