This is a video from one of my favourite YouTube channels Ghost Watching and this particular video shows the photo that Ghost Watcher took when on a family visit to the ruins of Tintern Abbey in Monmouthshire, Wales in 2008.
Tintern Abbey, Monmouthshire, stands by the River Wye and it was founded by the Cistercian monks in 1131 AD. It sits close to the Welsh and English border. The monk figures can be seen on the first floor but there are no actual floors left in the building. Could these figures just be down to the angle in which the photo was taken so that background walls could cause the effect of looking like 2 figures of monks? I think I need to visit these ruins as it's not too far from Tewkesbury!
The Ghost Watching channel has a great catalogue of spooky videos to watch.
