Foundation Since 1580, during the
English Reformation, there have been
Jesuits living and working in
Spinkhill, serving the local Catholic population. In 1580,
Robert Persons,
Edmund Campion, and Ralph Emerson came to England in secret. These first Jesuits were sheltered at Spinkhill Hall, the house that became Mount St Mary's College. In 1620, a clandestine school was founded in
Stanley Grange near Derby. When this school was discovered and dispersed by the authorities, it did not cease to exist. It was moved to Spinkhill. The school was in buildings owned by members of the Pole family who were related to those living at nearby
Radbourne Hall. During the 1700s, it was recorded that there was a Catholic chapel in Spinkhill, a house for Jesuit priests and that they travelled to serve the Catholics in
Holbeck, Nottinghamshire.
Construction In 1842, after
Catholic emancipation, Mount St Mary's College was founded. It was originally called the College of the Immaculate Conception at Spinkhill and it was founded by Fr Randall Lythgoe, the
provincial superior of the Jesuits in Britain at the time.
Developments In 1939,
Barlborough Hall, an Elizabethan manor some two miles from Spinkhill, was acquired to serve as a preparatory school to Mount St Mary's College. On 16 July 1939, the then headmaster, Fr Ralph Baines successfully petitioned the
College of Arms to give the college its own coat of arms. This was still used by the college up to its closure. During Baines' Headmastership from 1939 to 1945, he was also accepted into the
Headmasters' and Headmistresses' Conference, thus establishing the college as a
Public School. In 1979, girls were admitted as day students. From 1984, girls began boarding in the school. In September 2006, Mount St Mary's became its own charitable trust. The
Society of Jesus transferred the two schools to the Mount St Mary's Trust. While legally separate from the Jesuits, the college worked with them to maintain the Jesuit mission and identity of the college. On 30 July 2025, after the end of the school year, it was announced by the board of governors that the college and Barlborough Hall School would immediately close. The board said that the closure came after "increasing financial pressures, in line with the wider challenges affecting the independent education sector in the UK".
