Exploring around Suurupi again. This time a part where I had not been yet.
Suurupi sea defense artillery battery ruins.
Here is a quite long system of tunnels connecting 4 battery ruins.
The tunnels are in a great shape.
But also quite dark.
Light shafts for the little sunlight.
3 of the batteries had a round tunnel around them.
Nature taking over.
Here were some small stairs to get out of the tunnel to the battery if you wanted.
This tunnel was the longest, maybe almost 100 meters?
This is the exit/entrance to one tunnel also.
This is a new looking grate so you don't fall into the tunnel through the hole.
I have some more photos near that place that I will post soon. Thanks for looking.
