Fort Nelson will ring to the sound of guns from the Napoleonic period on Sunday during two gun firing demonstrations and weapons inspections.
Uniformed gunners will fire the historic guns at 1pm and 3pm at the Royal Armouries Museum, Fort Nelson, which is home to the national collection of artillery.
Re-enactors from Ubique Right of the Line will fire a British Bronze Six-Pounder gun, which dates from the last few years of the 18th century.
HMS Loire will also fire a French Imperial Bronze Six-Pounder, which was cast in Holland in 1813 for the French Republic. This was nicknamed Le Fameux (The Famous).
Fort operations manager Nigel Hosier says: ‘Each demonstration will be followed by a chance for visitors to inspect the guns and to ask the volunteer gunners for more information, and questions.
‘Museum admission and parking are free and it’s a fascinating day out for all the family.’
In 2011, the heritage attraction underwent a £3.5m redevelopment to create a museum for the 21st century, supported by a grant from the Heritage Lottery Fund.
