The centenary year closes where the school has marked its anniversaries since 1952: Salisbury Cathedral, on a Saturday afternoon in September. The service is about an hour. The school choir sings, current students and alumni read, and the address is given by a former pupil. It is a school service rather than a formal one, and there is no dress code beyond what you would wear to the Cathedral anyway. Seating is unreserved and the Cathedral holds far more than we will need, so nobody needs to arrive early to be sure of a place. Tea afterwards in the cloisters. Anyone connected with the school is welcome, including people who never attended it.
