I wanted to build something in Terraria, so I searched for medieval castles and found this beautiful castle from Japan, Matsumoto and I really wanted to try building it. So yesterday I spent a couple hours on building it, and i hope it turned out okay. Of course, it's hard to make a 3d Castle into a 2d model, but I tried my best and I think it turned out okay. The World is Large and on Normal mode, so if you want to play on it in Expert you'll have to convert it first. I haven't touched the world outside the castle, and the ground it stands on, so if you want to use it as a world to play on, it is untainted and new.
