Veterans Minister Graeme Dey will formally open the Moffat Trench at a military museum in Aberdeen later this month.
The MSP for Angus South, who was educated at Harlaw Academy in Aberdeen, has supported the Gordon Highlanders Museum in the past and will celebrate its newest visitor attraction on March 25.
He will be joined at the ceremony by Dr Margaret Moffat, the daughter of Colonel Frank Moffat, who was awarded the DSO for his actions in 8/10th Battalion on August 30, 1917, during the Battle of Ypres.
Work began on the trench project at the end of last summer and museum chief executive, Bryan Snelling, is hopeful it will prove popular with visitors.
He thanked the Moffat family for their assistance with the project.
He said: “We regard the Trench as not just a fitting memorial to the Gordon Highlanders of the Great War, but as a way of ensuring that today’s school children can continue to learn from the lessons of the past.
“We have attempted to make it as realistic and authentic as we possibly can and recreate an exhibit which we believe will be both a legacy and a remembrance piece.
“It’s a focal point to remember the soldiers who served in the trenches and witness the conditions they would have gone through.”
Dr Moffat is now in her 90s, but used to work as a volunteer at the museum.
She said: “My father did not want future generations to go through what he had experienced. Building this trench and seeing how it has come together will help young people connect with the past.
“I hope it will renew in them a determination not to repeat the mistakes of the past.”
