Early backers donated £1 million and those behind the heritage appeal today announced a further £250,000 has now been pledged.

The redevelopment will see display space increased , creating an area for special exhibitions, and educational interpretation and reunions are among the initiative’s goals.

Appeal director David Noble said he was delighted to announce £1,250,000 has already been raised or pledged since the heritage project began in September.

“This is indeed a magnificent start to the appeal and we have been greatly heartened by the very generous support that has come from so many people in Scotland and beyond,” he said.

“However, we still have a long way to go to reach our target of £3,230,000 and further support is vital if we are to realise our aim of preserving the heritage of The Black Watch for future generations.”

The Black Watch is Scotland’s oldest Highland regiment and enjoys a global reputation. Backers have spoken of their desire to see the story of the regiment’s history held in surroundings “worthy of its traditions”.

Among those backing the project is its official patron, Prince Charles, who wrote in the appeal’s brochure, “I was enormously proud and honoured to be appointed Colonel-in-Chief of The Black Watch in succession to my grandmother, Queen Elizabeth, The Queen Mother, who had been Colonel-in-Chief for more than 60 years.

“I am delighted to give my support and encouragement to this appeal, designed to safeguard the memory of a unique part of the British army and of Scotland’s proud military and cultural heritage.”

Appeal chairman Lieutenant General Sir Alistair Irwin believes the project will ultimately showcase the qualities displayed by the men of The Black Watch and hopes it will inspire younger generations.

Education is an important aspect of the appeal vision, he said. Support for The Black Watch Appeal can be given at www.theblackwatch.co.uk.
