At Thornton College, we are proud of our long and distinguished history. From our earliest mention in the Domesday Book in 1086 to the transformation of our Manor House in the 19th century, we have stood as a witness to centuries of change. Since our founding as a Catholic girls’ school in 1917 by the Sisters of Jesus and Mary, we have been guided by a deep commitment to excellence, compassion, and personal growth. Each milestone marks a chapter in our story, shaped by generations of students, staff, and families. Below is a timeline of key moments that reflect our evolution and enduring values.
