"Fortress that dominates the moats and the embankments beyond the moats"
This drawing depicts a corner of castle with two angular fortifications. One of them is contained in the walls perimeter, the other juts out of the corner of the fort. The two constructions tower over a moat that was not dug round the building but made by means of a toe wall and an embankment. What is particularly interesting and innovative about this defence system is the location of a row of cannons on the jutting stronghold, in order to be able to shoot at the prospective attackers who climbed the earthwork. This defence system is planned to arrange a sequence of grazing fires aimed at the assault troupes in the points where it was difficult to advance - the embankment, the moat, the curtain and the path for walking along the top.
The model is based on the drawing:
