[2][citation needed] The first building was in 1708 when a "school house" was built in part of the filled-up moat outside the city walls.

The school's playing fields and swimming pool were originally by the River Medway off Rochester Esplanade; they are now off Maidstone Road, Rochester, next to the area known as Priestfields (not to be confused with Gillingham FC's stadium, Priestfield).

An annexe (now known as P block) was built at the Maidstone Road site in the 1950s, housing only the second and third years.

By the early 1960s, the entire first and second years, and 3A and 3B were located there and 3G and 3L moved to the temporary buildings in the upper yard at the High Street site.

In the 1990s, a sixth-form centre was constructed, and at the turn of the century, a maths block was created upon the old staff car park.

In 2006 the school scrapped its A-level computing course, despite having received specialist funding to teach the subject.

After positive results were achieved by the pilot group, the option to take computing at A-level and GCSE was reintroduced in 2013.

[4] Founder's Day is held on the first Saturday of July: pupils attend Rochester Cathedral for a morning service and return to the school in the afternoon for sports and other activities.

The English department has since been rehoused in the old art and technology classrooms opposite the hall.

In Autumn 1945, new interest had been added that year to all forms of athletic sports by the revival of the House System.
