One of the building's better features is its entrance hallway. Here are a couple of shots I took looking toward the building's entrance.
Frankly, it was quite dark in the building and I wound up taking these shots (as well as each of the shots below) at f/5.6 for 1/25 second at an ISO of a whopping 4000. Not too bad, actually. I thought the individuals in the photos helped to create scale.
At one point we needed to walk down a couple flights of stairs through an arched hallway, and I took the following shots. The first looking down (with Geri and Tobias, my daughter's fiance, providing perspective). I thought this had an almost Kafka-esque feel to it.
And the second from the bottom looking back up.
Finally, as we were leaving the building I noticed a sign in a side corridor that said, Spiral Staircase, and I took the following shots, in this case looking up and looking down.
The staircase was cordoned off, so I didn't have access to the floor at the bottom to get the full effect of the spiral stairway. Instead, I had to lean over a railing to come as close as I could to a central shot. Also, once I reviewed the last shot in post processing, I noticed that there was a piece of paper lying on the lower level floor. I managed to remove it in post processing. I had originally rendered these shots as black & whites, thinking that that would help emphasize the curved lines. But in the end I stayed with the color, which I thought was quite rich looking.
