This is a log pallisade mound fort model I designed years and years ago.
It's pretty simple with a single gate tower and modular straight wall and corner sections that paperclip together....so you could in theory make a really big fort. Really big.
It's fairly generic, so it could be iron age, medieval, or even wild west.
Thanks to Mproteau from Cardboard Warriors for the great build photo.
So here's the link to the Wooden Fort:
