Sometimes I go into a location expecting to find something entirely different, this was one of these. We are exploring one of the German weapons testing grounds near Jutbug and Kummersdorf, here some very special tests took place, entire forts were constructed to determine their soundness in war. The very tests the French should have done before WW1. Here some of the real groundbreaking fortress design and building techniques were tested against the heaviest of guns. Truly here is the birthplace for the concrete and rebar fort. And even better the very fort for one of my favorite forts were laid here, cant wait to show you.
