This weeks Photo Friday: “Depth Perception”

It has been a wee while since I completed a Photo Friday.
As soon as I saw the subject for this last week, I knew exactly which photograph I wanted to use.

This is one of the entrance to the tunnels at Stony Batter.
Stony Batter is a WWII defence installation on a remote eastern side of Waiheke Island. It is now a Category I Historic Place and these tunnels worm their way throughout the hillside.
