You will no doubt have read that we recently discovered a new rock cut tunnel within the Banqueting Hall. This small tunnel leads from the trench in the Banqueting Hall floor, through the bedrock wall and into yet another chamber. We have long suspected that there could be another chamber or passage alongside the Banqueting Hall. So the discovery of this was very exciting indeed. Joseph Williamson’s long lost subterranean World continues giving up its secrets.
The rock cut tunnel is around 3ft deep, extending into the bedrock wall of the Banqueting Hall. We have managed to get just inside this chamber, though we were initially asked not to dig the infill out from within the chamber until it was established that the brick built arched roof was complete and of course safe. We are delighted to report that we have completed the required method statement and risk assessments to enable us to dig out the infill in a safe and controlled manner so that the arched roof can be examined for safety. Once we know that the roof is complete and safe, we will of course aim to empty the chamber.
However, first impression suggests that the arch is intact and safe. We sent a GoPro camera up to the top of the roof on a long pole to get a good look at the roof and to our surprise, there is yet another nice sandstone arched tunnel as can be seen in the video.
So where might this arch take us? Well we would like to think it will take us to the long lost Great Tunnel. It is possible, given this chamber’s depth of approximately 37ft below ground level. Time will tell…
It will take us quite a while to empty the infill from inside, giving us full access to the chamber. Though we will of course update you with news on this dig as and when we have it. So stay tuned to Twitter, Facebook and of course right here for updates.
