12 Hidden Medieval Northern Border Castles

Today, in this big bumper documentary - I have travelled far-and-wide around the northern border between England and Scotland, discovering 12 castles that I believe help uncover the history of the Border Wars from the War of Scottish Independence, the Hotspur Rebellion, to the Scottish invasion of King James IV and Cromwell's invasion of Scotland during the English Civil War.

I hope you enjoy this video and feel free to let me know how many castles featured in the documentary that you previously knew about!
