The second half of XIX and early XX century is a tipping period in the history of fortification. Then came a transition from modern fortification that appeared through the polygon and bastion system to modern fortification that means distributed. In this period fortification is particularly highly developed on the territory of Poland. This was the result of the political situation in the country, that remained under the protections of Austria, Prussia and Russia, and the deterioration of relations between the former allies.
