This castle is called Kost in Czech. “Kost” means castle and it is known as a gothic castle.
Not sure why it’s known as gothic castle since if you search for images of it, they look alright to me… From the outside.
There’s not much picture from the inside but it does gives you an “RPG” feeling doesn’t it ? I wish I could visit Czech some day.
The castle currently privately owned by Czech Counts family Kinskż dal Borgo .
Building this might be a little bit hard as the instruction given is in Czech. There’s a picture guide but you have to use your imagination for most of assembling.
