Thank you to Andy Merrylees for the recollections below.
"I saw your photo off the
remains of the wall close to where Granton castle used to stand.
If I recall, when I was a
teenager I am almost certain that there was a tunnel passageway that we
went into near the dirt road, at the east end of the road facing south."
"I remember a small group of us
went into it to find out where it would go. We eventually came across an
old type of solid wooden door - the type that would have built
around the 16th century.
Of course we tried to open it,
shoulder it, but to avail."
anything about this?"
