Among the guests at the Seagoe Hotel event were former head girl Lady Mary Peters; Deputy First Minister Emma Little-Pengelly and Peter Cardwell, presenter and chief political commentator at TalkTV.
As well as providing the ideal opportunity to rekindle memories and catch up with old acquaintances, the evening helped raise funds for the Mary Peters Trust and the School Fund.
Photographer Tony Hendron was there to capture some of the atmosphere of this special event in the school’s history.
