In reply to j_duds:
They do appear to have started building here again after several years of inactivity.
When I first visited this place in 1993 there was building work above the crag and shortly after that the crag was 'closed'. This was when the fencing was added and the routes on the right as you walk in blocked off although few people appeared to actually be stopped from climbing since the path was always open below the crag.
This situation of pretty much tolerated access persisted until around 2002/3 or so when there was once more a burst of building activity above. I am not sure whether the crag was officially closed during this period however a lot of that metal work and debris was lobbed down at this time so it did appear that the crag might have become a bit dangerous.
Then the building stopped and everything was back to normal, and new routes were added to the sector beyond Blobland. Now that there is a recession it appears that the building work has started again! Let's hope they don't start lobbing more rubbish off from above as before.
I'd be interested to hear reports from people who do try and climb there. Is everyone getting thrown off? Is the 'person' doing the throwing off actually connected with the construction? I suspect that access will become difficult while there is continuing construction, and this may go on for some time since it is a massive development, but after that the crag will be open once again.
