We were delighted to welcome the Class of 1974 back to school on a wonderful, sunny Saturday in September. Over 25 alumnae, some of who had not been back to school for 45 years, gathered together from all over the UK, sharing photos, memorabilia and stories.
From the noise level, it was apparent that everyone had a really enjoyable time, catching up on each other’s news and touring the Prep and Senior schools!
