What island is the world’s smallest “condominium?”

In international law, condominium refers to territory that is governed by multiple sovereign powers who formally share duties without necessarily dividing the area into national zones. Pheasant Island (Konpantzia) is an uninhabited landmass on the Bidasoa River separating France and Spain. Stewardship of this 1.69-acre island alternates every six months: it falls under Spanish rule from February 1 through July 31 and French control from August 1 through January 31 each year.
