Between years 1935 – 1938, there were very uncertain times in The Czechoslovakia. Germany was arming, so Czechoslovak government expected some kind of military interventions. Because of that, many military fortresses were built on norht, west and south borders. This is one of them, in Krkonoše – close to the spring of the Labe river. Because of the circumstances, these concrete fortresses were planned and built very quickly.
Ahoj!
