From the Bolwerk in the English garden

I am standing on the bunker that served as Command Post Connections from 1940-1945 and looking out at the Franekerpoortsbrug (1608).
From this post, the Germans keep the Frisian coastal defenses under control.
The coastline is part of the Atlantic Wall, which runs from Norway to Spain.
The bunker is 20 meters long and 5 meters wide
