Greece and Italy established their maritime boundary through two bilateral agreements, one in 1977 and the other in 2020. The line was based on a modified application of the equidistance delimitation methodology. Starting in the Strait of Otranto, the line proceeds into the central Mediterranean Sea in a southerly direction for 304 nautical miles. The boundary line is defined by 16 coordinate points that are interconnected by 15 geodesic line segments.
