The world has never felt so still, so calm and so quiet to me as the evening when I stood inside the central chamber of the long barrow at Fingask Castle in the Braes of the Carse in Scotland. The skies, the darkest tones of obsidian and the stars clustered as if guardians of the moon.

I’m standing in a structure that’s been built by a small team of men led by seventh generation stonemason, James Davies whose father, Geraint Davies is a master stonemason and designer of long barrows. Each barrow is drawn by hand and in 2014, Geraint completed the long barrow at All Cannings, Wiltshire – thought to be the first Neolithic-style burial mound to be built in the UK for more than 5,000 years. It can be described as a columbarium – with more than 200 niches and, within these, cremated remains can be placed in urns.
