A crack at building Vauban fortifications.

I recently bought a building block set of styrafost bricks. The idea is to cut and shape them into what you want to build.
My project shall be to try and build the Dauphin bastion and gate of Louisbourg. I have a table big enough to achieve this.
The first thing I need to do is to figure out the footprint of the bastion and gate. As well, I shall have to see what parts I have to build the Dauphin Gate.

The business end

birds eye view

need to build some ramps

seem to fit.
