Visitors to Pendennis Castle this month will be offered an exciting behind-the-scenes glimpse at English Heritage's vital conservation work. 

The charity, which is tasked for caring for over 400 historic buildings, monuments, and sites including Stonehenge and Cornwall's Tintagel Castle, is holding a 'Conservation in Action' day for visitors to learn what goes into maintaining these special places for generations to come.

The event is taking place in the grounds of one of the most iconic spots in Falmouth on September 14. It will bring together different departments from English Heritage as well as specialist contractors and suppliers.

Those in attendance will be able to try their hand at lime plastering, making a handmade clay tile, and slate cutting. There will also be demonstrations of high-level inspection work using abseiling ropes, intricate clay carving and 3D scanning of Pendennis Castle's keep.

Questions are encouraged and visitors will be able to find more information on English Heritage's apprenticeship programmes and the hidden gems in the area that they can visit for free. A full list of stands taking part in the event includes:

• English Heritage Apprenticeship Programme
• English Heritage Building Conservation Team
• English Heritage Free Sites Team
• English Heritage South West Estate Management Team
• Cornish Lime
• Keymer Tiles
• Moulding
• Sally Strachey Historic Conservation
• Williams & Burrows Heritage Repair

The 'Conservation in Action' day will take place between 10 am to 5 pm (14 September). Entrance to the event is included in the daily ticket admission price to Pendennis Castle, which is free for English Heritage members.

Pendennis Castle is one of Henry VIII's finest seaside fortresses and boasts a keep with panoramic views out to sea, a collection of historic weaponry, and an exhibition of wartime tales.

English Heritage Estates Manager, Martin Roscoe, commented: "Each of our sites are unique in their construction, but with that comes a unique set of challenges when it comes to looking after them. That's why English Heritage needs the expert care of its dedicated Estates Team and specialist contractors who can carry out maintenance using traditional skills and materials.

"However, many of these heritage crafts are in decline, so it's important for us to celebrate these and inspire the next generation to get involved in our sector. We hope our event at Pendennis does just that, as well as providing an exciting day out in Cornwall."

This special event at Pendennis Castle comes a month after the news that English Heritage is launching a new apprenticeship programme and the creation of a heritage skills centre in East Anglia, aimed at saving endangered heritage skills and crafts.

The work has been funded by a £11.2m donation from the Hamish Ogston Foundation – the largest in the charity's history – and will safeguard the future of 34 flint castles and abbeys in the East of England.
