Downside School (formally The College of St Gregory the Great, Downside but simply referred to as Downside) is an 11–18 mixed, Roman Catholic, independent, day and boarding school in Stratton-on-the-Fosse, Somerset, England. It was established in 1614 and is located in the Roman Catholic Diocese of Clifton.
Originally a school for English Catholic boys, it was established by English and Welsh monks living in exile at Douai, France. The monastic community returned to England in 1795, with both the community and its school initially housed in the Shropshire home of Sir Edward Smythe, a former pupil. By 1814, the abbey and school had been re-established at their present site, in Somerset. Downside School became fully co-educational in all year groups in 2005.
