Founded in 1934, Glyndebourne, three miles east of Lewes, off the A27, is Britain’s only unsubsidized opera house, and the Glyndebourne season an indispensable part of the high-society calendar. It’s undeniably exclusive – and expensive – but the musical values are the highest in the country, using young talent rather than expensive star names, and taking the sort of risks Covent Garden wouldn’t dream of. An award-winning theatre (seating 1200) has broadened this exclusive venue to a wider audience, and there are tickets available at reduced prices for dress rehearsals or for standing-room-only.
