The granite cross, a stark reminder of the Battle of Flodden Field in 1513, was put in place on September 27, 1910 by members of Berwickshire Naturalists Club.
It was therefore fitting that the club's current vice-president, Patricia Payne, was able to attend the centenary ceremony.
The Remembering Flodden project has been responsible for considerable improvements in interpretation and access at the site over recent years.
Clive Hallam-Baker, one of the trustees, has been instrumental in much of the significant research into the battle.
Its quincentenary in 2013 is set to be a period of focus and reflection across the Borders and north Northumberland.
"We are particularly keen on genealogical aspects," explained Clive. "We are all increasingly aware of our heritage and can trace it more readily through internet resources.
"We know of one local man who can trace his ancestry right back to a soldier who was recruited to fight at Flodden, and we are preparing a new DVD documentary as well as an exciting new use for the red telephone box in Branxton village!"
A while ago, Lord Joicey of Ford and Etal Estates brought together a committee to help local communities and groups to mark, in their own way, the 500th anniversary of the battle itself.
It has been successful in its application to LEADER Northumberland Uplands, appointed a project officer and is now in the initial phase of plans.
Representatives of many local groups, societies and larger organisations have already met on three occasions to discuss the plans, and these meetings have been hosted by Ford and Etal Estates on whose land the battlefield lies.
A major thrust of the anniversary plans will be the linking together of local sites directly connected with Flodden in an interpretation of its lasting heritage.
The creation of this network of sites is the main feature of the LEADER-funded work.
Following a pattern established elsewhere in Europe and referred to as an 'eco-museum', this will be the first such grouping of its kind in England. It embraces sites and associations that relate to Flodden.
"There are many sites, both locally and further afield, which provide a real sense of place and of common heritage," explained Lord Joicey of Ford and Etal. "They tell the story of Flodden and make us understand the heritage it has left behind.
"Sites such as the Flodden Wall in Edinburgh or the medieval Flodden Window in the small village church in Middleton in rural Lancashire are important parts of this heritage.
The concept of linking together sites that are geographically scattered but connected to a common heritage is probably set to expand in this country."
