Previously, we made a documentary on the history of Loch Thom in Greenock, Scotland. Robert Thom was the engineer behind this project and other large-scale hydraulic projects and water filtration plants. We were recently on the Isle of Bute and took the opportunity to visit the grave of Robert Thom.

Robert Thom died in 1847, so the gravestone has been exposed to the elements for a long period of time. The stone has some staining and weather marking on it, but the stone itself is in good structural condition with no obvious breaks or cracking. There is some settlement, and the stone does have a slight, but noticeable lean to the right. This should probably be addressed before the lean progresses and makes the stone less stable.

Whilst visiting the location, we also took the opportunity to create a photogrammetry-based 3D model of the stone. We have created a YouTube short to show the current condition of the stone. Unfortunately, on the day we visited, it was very sunny and there was a noticeable shadow cast on the stone with the sun being high in the sky. We do plan to go back and create a better quality model of the stone on an overcast day.
