They show pupils and teachers at Notre Dame School around the turn of the new millennium.
Pupils are pictured in their finery on prom night and embracing after opening their exam results in this retro gallery.
The victorious school football team, national science award winners and a visit by Ofsted also feature.
Students are also seen with famous musicians Javine and the band Feeder, with the latter taking part in a cookery class at the school.
Perhaps you will spot one of your old school friends in these pictures, or a favourite teacher.
