Quote:The postartillery walls are maded of earth, but almost always have covered with concrete to avoid the erosion by meteorologicall agents (rain, snow, wind, etc.)
The curtain walls were rather made with fired bricks with earth in between. I know because I have been lately often to the last German border fortress of the old artillery days. :wink: Concrete is much more a feature of 20th century fortifications.
