This is an interpretation of the Belverde Castle near Potsdam.
This castle is a real splendid building for your Minecraft world. I based it on the castle Belverde on the Pfingstberg near Potsdam, the castle garden is freely invented.
You'll need oodles of sandstone (or whatever material you prefer to use) for this project. If you want to build it in survival mode like I did, I recommend enchanting a few slide picks with efficiency IV and durability III, then raiding a desert temple. The roofs are made of clay.
