An 'ecomuseum' recognising places and communities associated with the Battle of Flodden is hoping to expand from 12 regional sites to 40 around the UK.

Flodden 1513 has identified 28 new sites it wants to add to the museum with 17 likely to join the project, including Linlithgow, Stirling and Edinburgh Castles in Scotland, the Mary Rose in Portsmouth and the Ord of Caithness.

This year marks 500 years since the battle took place, taking the lives of 15,000 Scots and English soldiers as well as King James IV.

An ecomuseum links sites associated with a central theme but does not have any central ownership or control, with local communities managing heritage sites in their own area.

Examples of the first sites involved in Flodden 1513 are The Flodden Wall in Edinburgh and Heatherslaw Corn Mill in Northumberland.

Flodden 1513 director Alistair Bowden said: "[The sites] can bring together the many ways in which the consequence of Flodden are still felt and witnessed - in literature and art, national and local politics, archaeology, archives, family stories, churches, monuments and much more."
