OK Q, please tell me if I am heading in the right direction…

The MAP yields pictures at Washington (owl), Pyongyang (phoenix), London (spider), Vatican (key) and I think I am missing one.

If you link these together, with Washington being the left terminus of an arch and Pyongyang being the right terminus, then a KEYSTONE forming an upside down triangle appears with nodes on London, Vatican, and maybe Poland (old Danzig)?

Am I close?
