The Big Guns are being fired at Fort Nelson for a free Firepower at the Fort event on Saturday 7 and Sunday 8 October.
Visitors will be able to experience the power and might of a range of artillery from the World Wars, including anti-tank guns and field artillery.
Uniformed members of the Garrison Artillery Volunteers will fire the artillery for this special event with firings at 11.30am and 2.30pm.
The gun crews and artillery experts will be on hand to talk about the guns and the firing drills, as well as displays of small arms on site.
There will also be static displays, performances from a singing duet, theatrical displays by re-enactors and a museum trail and face painting for younger visitors.
The event is free, but tickets need to be booked in advance as numbers are limited at bit.ly/3R9PFmc Car parking £3 – pay on arrival.
Events Manager, Elizabeth Puddick, said: “We are absolutely delighted to have gun firing back at the Fort for this one-off special weekend.
“Royal Armouries is home to the national collection of artillery and to be able to fire some of our exhibits and show them in action will really bring history to life.
“The event is free, but we have limited numbers so remember to book in advance to guarantee entry – bring all the family for a really remarkable weekend.”
