Repulse Bay Eucliffe Castle.

I think that PB17 is just visible on the right - standing further out of the sand than it is in 2018.  There also appears to be a square military(?)  structure on the shoreline in front of the two white retaining walls in front of Eucliffe.  I am fairly certain that the cave into which the survivors of the December 1941 massacre crawled (still visible just off the promenade and behind a chain link fence in 2006) is in the darkish section at the bottom of the cliff, just above the shore and directly beneath the trees at the bend in the road.  Andrew
