The Roof-top synagogue was a private synagogue built on the roof of the home of Philip Salomons on the Regency-era Brunswick estate in Hove, now a constituent part of the English city of Brighton and Hove. It is a small octagonal edifice on the top of a glass room forming part of the fourth floor (in British terminology, not counting basement or ground floors), in reference to the Dome of the Rock in Jerusalem.
