Well, the US has a short history, compared to Europe or other parts of the world, so no wonder there are no castles.
Thanks @coolmidwestguy, I tried to cover as much as possible, show you the interesting parts and share my experience, so the readers can have a short trip though my blog to the place.
Have a nice weekend and stay tuned as I'm posting about the interior next week.
I passed through Europe when I was much younger I could have seen some probably. I was more interested in there drink cultures and wasted a lot of daylight sleeping in. I was in Germany for 5 days. Look forward to the inside views 😁
