Great post love reading your travel tips about the Czech Republic. This post I noticed that in the picture it looks like the side of the castle walls is made out of a weird shiny panneling? Now I might be wrong as I can't see if its made out of stone or not but I saw the same type of building material in Prague as well near the Prague castle. I had never seen a building like that be shiny and it caught my attention. Is this type of building material common throughout the Czech Republic or just in Prague?
