You may be wondering why I haven't shown you any of the art. There's a simple answer - photography of the art was not allowed. The Boros Sammlung is actually a private collection that Christian Boros, the owner and resident of the bunker, has been kind enough to open up to the public. I did, however, sneak these two shots on my way to the toilet before the tour started.
I don't recall the name of the artist who created these sculptures. It's a shame I couldn't really get the whole room as it's quite open, not what you'd expect in a bunker. Hope the lack of art won't stop you from coming back tomorrow for more on the bunker.
