Nestled beneath the Downs, three miles east of Lewes, this world-famous opera house combines first-class productions, a state-of-the-art auditorium, and a beautiful setting. Tickets are very expensive (the cheapest start at around £85, though for many productions it's twice that, rising to around £250), and you have to book months in advance. But it's worth every penny to aficionados, who traditionally wear evening dress and bring a hamper to picnic on the grounds. The main season runs from mid-May to the end of August. Save money by booking standing-room tickets (from £10), or look out for special nights when adults under 30 pay just £30.
