So, basically me and a mate went exploring looking for a swimming spot- with no idea what we would find.
This gate was the first thing we found, totally mystified us- could not figure out why an abandoned quarry would have this… Possibly the mining explosives need to be secure??? But we went inside anyway!
Once past the gate there was weird white stuff all over the place- we surmised that the tunnel was a salt store for gritting the roads or something, or maybe the explosives were packed in salt to keep moisture out of them.
This is the other end of the tunnel, we knew there was something weird now, because it was not made of stone- it was made of fibreglass… A lot of head scratching… But, we spotted the security guard at this point and had to scarper back down the tunnel
Once into the main area this was what we saw- still no idea what it was… We couldn't figure out why they were refurbishing a castle in the middle of a quarry…
THE PENNY DROPS!!!!!!!!!!
Still not sure which Castle it is… Some bits look like Winterfell but some bits dont… I think it might have been little bits of loads of castles…
EDIT: Thank to TheGhostofLionelHutz for finding this- There *IS* parts of Kings Landing filmed here!
