Actually, they work fine on my phone, it must just be my work's network that blocks Flickr.
The hatch to get down inside it is still there but it is now sealed up. I found it a few years ago and made the mistake of telling a friend who has some shady friends. They camped out in it and stuff (even though it was horrible!) so I'm assuming the golf course owner clocked on to people climbing in and out of the ground and now it's welded shut.
You can still see the hatch... If you go up Prieston Road, right to the top past the golf club pub then the next right which is like a farm road. Up that round about a mile there is an old barn type structure for storing the rollers for the green. If you walk on to the golf course and head to the woods nearest the road it's hidden in amongst them.
It was small and there wasn't much to see but no one had been in it until I found it so it was undamaged and had sealed bottles of potassium iodide liquid (to prevent the body's absorbtion of nuclear radiation!!).
