The island is a
condominium, the world's smallest, under joint
sovereignty of Spain and France; for alternating periods of six months, it is officially under the governance of the naval commander of
Hondarribia, Spain (1 February – 31 July) and of a French viceroy (1 August – 31 January). Currently, the French position of "deputy director for the sea and coast of the Atlantic Pyrenees and Landes departments" carries the title of "
viceroy of Pheasant Island", an unusual name in the French Republic. One of the French officers with this title was Julien Viaud, better known as the writer
Pierre Loti. In practice, it is administered in turn by the mayors of
Irun (in
Gipuzkoa, Spain) and
Hendaye (in the
Pyrénées-Atlantiques, France). == Geography ==
