The school sits on the site of a demolished country manor, Etwall Hall, traditionally of the Port family who were the wealthy landowners/farmers of the parish. In 1952, the
Derbyshire County Council bought Etwall Hall from
Reg Parnell, the famous racing car driver. The hall had been used during the
Second World War by the
British Army, first as a petrol depot and later as an equipment supply centre and been left in a somewhat dilapidated state. After its demolition a
secondary modern, Etwall Secondary School, and a secondary
grammar school, John Port Grammar School, were built on the site. In 1965 they were amalgamated to form the John Port School that occupies the site today. The name of the Port family, who lived at the hall, has been associated with Etwall since the 15th century. The family's most famous son,
Sir John Port, was the founder of the nearby
Repton School and committed to the furthering of education for young men in the village. It therefore seemed entirely appropriate that the new school was named after him. ==School site==
