Best kept secret in OKC!! Loved all the pictures and history represented in the halls. One down side is it was a litrle hard to find. Definitely worrh a visit!

Pretty cool to explore and read up on some local Oklahoma City art and history. The glass pyramid by the BancFirst Building was the first entrance I was able to find. Once inside directions were easy to follow. Recommend this place if you are into art and local history.

We enjoyed exploring these tunnels for at least a couple of hours. I learned more about OKC in that time than perhaps any city I've been to (except London - I read the book - but I digress). It was also nice to be out of the heat.There were two photos that, taken together, don't seem believable as described. According to the captions, one was taken of OKC April 22, 1889, and the next on May 13, 1889 - just 3 weeks later. Not only has an entire city appeared in 3 weeks, but additional rail lines, and an outhouse added in the foreground. What really seems implausible, though, is a massive pile of dirt in the first photo has disappeared 3 weeks later, with no sign it was ever there - even the grass has grown back perfectly. In three weeks. I'd love to know how the dates were authenticated.We can learn a lot from our elders, so I really enjoyed the quotes and photos of people who had made it to be 100 years old.We entered through a door in a parking garage, but there's an escalator right up front in the BancFirst building that's probably easier to find.
