The tunnel beneath Castell Brogyntyn is well known, but the parkland boasts a second, the location of which is kept secret by those in the know, to protect the four lesser horseshoe bats that live within.
(Lesser horseshoes are restricted to Wales, the West Midlands, and the south-west of England. There are about 50,000 individuals in the UK. Their worldwide International Union for Conservation of Nature classification is Vulnerable, i.e. at high risk of extinction.)
The tunnel has Y-shaped adit-like entrances at both ends. It is constructed from the local rock, stacked so as to create a deliberately rustic appearance.
About ten or so yards long, including the splayed entrances, the tunnel curves gently underground, is broadly S-form in plan.

I've been trying to figure out where this is, as I've been all over Brogyntyn and never found them. Can you help?
Steve, I’ve only just seen your comment. Drop me an email - details on the blog side-bar - and we can arrange for me to show you the tunnel. Regards, YMGW.
