2. When i was a minor, my father (a naval officer in the Hellenic Navy at the time) took me to HS PAPANIKOLIS, a WWII submarine that served under the Greek Flag (Hellenic Navy) during WWII against Italian warships. It was constructed in France. below find some pics but the website is in Greek. I could not find something in English.

3. When i was doing my obligatory 21 month navy service in the Hellenic Navy i have visited a type 209/1100 German-constructed submarine also serving with the Hellenic Navy called HS GLAFKOS III. These are 1972-1980 made and underwent extensive overhauling from 1999 and on.
Well thats it i guess...
