As the rousing wartime music rings out and the spectacular firework display set the sky alight, visitors can warm themselves with delicious burgers from the barbeque and a drink or two from the bar, while the children enjoy the traditional fun fair.
The gates open at 6.30pm and the fireworks get underway at 8.00pm. All proceeds go to the Bletchley Park Charitable Trust. Admission payable at the gate: adults £3, children £1. Season tickets do not apply for this event
