More Of Der Atlantik Wall

As we continue the examination of the Nazi propaganda filmstrip Der Atlantik Wall, the images begin to take on a much more military tone, with photographs of actual fortifications.  In the first picture below we see what appears to be barricades on a path or road near a beach. 

While I am certainly not sure of the subject in the next photo, it seems to show the tops of underground bunkers, with ventilation pipes and possibly entrances.
