Actually not similar, only the shape is similar. The trick with the "trace italienne" is that each tower (edge of the star) can reach and attack people below the other towers, so each tower is protected by its neighbors. As far as I can tell, Fort Bourtange never had towers for defense but rather relied on it's walls to protect it enough.
