The Vauban style of fortification had a great many variations. They could be found in many different sizes and configurations. This kit allows you to convert PaperTerrain's 4-sided Vauban Fortress (sold separately) into a 5-sided fort. The kit includes an additional bastion, replacements for all the walls, an additional gatehouse, barrack building and stairway. The kit is available with either a brick pattern or a stone pattern. Please note that this is NOT a stand-alone kit. It is meant to be used with the 4-sided Vauban Fortress kit, which is sold separately.
