An anti-aircraft gunnery training dome and military museum is celebrating three anniversaries in one at its upcoming open day.

This year, the Langham Dome Museum, near Holt, is commemorating a decade since being opened, as well as two 80-year anniversaries.

Scott Eltringham, manager for the Langham Dome Museum, said: "Next Sunday, we will be celebrating the arrival of the Australian and New Zealand squadrons, and the time when RAF Langham re-opened as an airfield in 1944."

The museum is marking the celebrations with a free event on July 21, from 10am-4pm.

Included in the event is an appearance from actor and aviator, Martin Shaw, who will be opening the day's commemorations.

Well-known piper, Jacob Millin, whose grandfather was famous piper for the D-Day Landings, will also be performing.

"There will be loads of other activities for visitors. We've got live music, mostly of the 1940s and 1950s era, a Sherman tank and re-enactors."

"Visitors can also enjoy lots of eateries and a special beer being brewed by Norfolk Brewhouse to help us all celebrate," Mr Eltringham said.

A spitfire will also be flying over the Dome, piloted by aviator Brian Smith.

The dome has long considered itself one of the early users of augmented reality.

In the early '40s, simulations of noise and conditions of an air attack were projected onto the inside of the dome to teach trainees how to shoot enemy aircraft in a safe but realistic environment. 

Mr Eltringham said: "The RAF decided it would be a good base to attack German shipping convoys that were coming from Scandinavia."

It is the only scheduled ancient monument in the country that is open to the public.
