It is mostly made of very thick concrete, with lots of little rooms housing collections. It was always a surprise what awaited us behind each closed door and each exhibit was very individual.
A particularly interesting one was the room full of dangling bricks...
Darren was very taken with a lady sitting on a zebra and I think that he would have liked to have taken it home, but it was about ten feet wide and nearly as tall so I don't know where we could have put it.
Unfortunately, I forgot to take a photo of the outside of the building but the inside is pretty impressive.
