St Albans School is an independent school in the city of St Albans in Hertfordshire, in the South East of England. Entry before Sixth Form is for boys only, but the Sixth Form has been co-educational since 1991. Founded in 948 by Wulsin, St Albans School is not only the oldest school in Hertfordshire but also one of the oldest in the world. The school has been called "Britain's oldest public school" by the Daily Mail. Nicholas Carlisle, in 1818, described the school as "of very ancient origin, and of great celebrity" and the Good Schools Guide describes St Albans as a "traditional public school, with a rich history".
