2. TAPP = Trans Adriatic Pipeline Project
A pipeline from the Greek/Turkish border at Kipros, a town in East Macedonia (Greece) that provided the main natural gas route to Europe (via Greece, Albania, Adriatic Sea & Italy).
It's key strategic value - it provided a new route to EU for gas, by-passing Russia (article on 2014).
The new source? 'The Caspian Sea'. Meaning IRAN (and Azerbaijan).
