France and Monaco established their maritime boundary through a convention that was agreed to in 1984. The boundary follows a series of loxodromes and an equidistance segment to create an enclosed corridor that extends in a southerly direction from Monaco’s coast into the central Mediterranean Sea. The corridor is two nautical miles wide and extends seaward for 100 nautical miles from Monaco’s coast. The two States agreed to establish this narrow corridor to provide Monaco with more equitable maritime space given its diminutive coastal front, which would otherwise have been quickly cut off by equidistance lines controlled on both sides by France’s mainland coast.
