I want to have a medieval city, but every medieval city needs city walls (ramparts).
And building Ramparts sucks.
So I came up with a cascading structure block method to build ramparts.
Each structure has structure blocks that will load the next segment of wall, bartizan (turret), crenellation, tower, or gate.
This "castle" was built entirely with structure blocks... with quite a bit of hand cleanup because everything does not always match up... also you will have to adjust the XYZ coordinates of blocks every once in a while because everything does not always match up.
This was a 24 hour build.
Before I go into it, I want to say I spent a bit of time watching various Youtube documentaries about historical castles. My favorite was Shadiversity. Shad has nothing to do with Minecraft, but you should watch his stuff if you do medieval builds

Why do medieval buildings overhang their lower floors?
Also I have an instructions-for-use post that tries to explain how things work
