I really wouldnt bother the place is absolutely fucked now; also new security are pretty on the ball.
Security were VERY on the ball last week just gone. I went for a quick look while on my way up to Aberystwyth. I'd never been to Denbigh before. The site is still very overgrown, wild and untamed so it's still a legit explore I think, although it is indeed heavily ruined and absolutely punked. It was still very rewarding to see the beautiful buildings peak out from behind the rolling hills on the way there however. The exterior is ridiculously photogenic amongst the surroundings. Like it's straight out of a gothic novel. Its the most asylumy-asylum I've seen anyway, almost a Hollywood cliche.
Access to the site is straightforward around the back. There's some buildings (and the partly sealed chapel) which are fairly open to being easily explored and provide some gentle urbex, once you cross the service road/track that's been shaved across the hill to aid security driving around. It's when you go towards the main blocks that an inner steel fence appears. This site management approach felt very similar to my Severalls explore in 2017 - sacrificial and nondescript buildings (except for the chapels) easily accessible in the periphery of the site and then an iron curtain around the main protected blocks. I'm assuming that this is some mandated design or instruction for dealing with these sites while they are on the approach to bing redeveloped?
Security were right on the ball and seemingly followed me around the fringes of the site, though I'm not sure if they knew I was there or not. But they were thorough and worked in pincer movements. It was a very close call so I left without investigating the inner fencing and therefore Denbigh is still 80% mystery to me. Another place left a little too late to explore me thinks. While driving back past the place very late that same day I saw them out with their torches and dogs again. I hope they are getting well paid for the constant exertion!
