Our visit here wasn't worth the journey - had we known in advance, we could have booked a tour inside but apparently you need to book 2-3 months ahead! We walked around as far as we could, on a wet day, which was probably good, as there was no shade anywhere, so the concrete would have been very glaring if it had been sunny. Photos were not allowed around the perimeter of the building and as its not a very "pretty" structure, that didn't matter much!!
