The building at 11 Dyke Road in Brighton, part of the English city of Brighton and Hove, was in its most recent guise (2014–2023) the Rialto Theatre and as of January 2024 was being converted into a live music venue, but it originally housed the Swan Downer School for poor girls, for whom it was designed and built in 1867 by prolific architect George Somers Leigh Clarke. The highly ornate brick structure, in a "freely inventive" European Gothic style, has also served as a chapel and an office since it was vacated by the school, whose pupils were recognisable around Brighton in their blue and white uniform. English Heritage has listed the building at Grade II for its architectural and historical importance.
