International protection of the territory
The whole area of Vatican City is under the protection of the Hague Convention of May 14th 1954 regarding the safeguarding of cultural heritage sites in the case of armed conflicts.
In 1984, Vatican City was registered as a world cultural and natural heritage site in terms of the UNESCO Convention of November 16th 1972, which guarantees the protection of such sites.
Vatican City State is also internationally recognized as a moral, artistic and cultural heritage site that merits respect and protection as a treasure that belongs to the whole of humanity.
Even though Vatican City has no direct access to the sea, by virtue of the Barcelona Declaration of 1921, it is allowed to sail its own vessels flying the papal flag.
However, the Vatican does not avail itself of this right at this time.
