I'll admit it, we only went to Montenegro in order we could say "LOOK!! Passport stamps!" I also REALLY wanted to see these. There were two of them, both identical and approximately 400 yards apart. Again, all I can tell you is they are remnants of the former Yugoslavian Navy property portfolio and that they were in much better condition than the one we visited in Croatia.... reason being they were utter b'stards to get at from land.
