Welcome to The Jungle

I spent a good while looking for this thing, and my suspicion is that the jungle has won. It would be inappropriate to cut down actual mature trees to get back to this bloc (it was opened in 2003, more than two decades ago at the time of writing) and I think the 'jungle' in question has simply overtaken the bloc. If there is a big fire, it may reveal itself.

Task: Prove that this bloc can still be found.
