Pheasant island

Pheasant Island, also known as "Isla de los Faisanes" in Spanish and "Île des Faisans" in French, is a small uninhabited island located in the Bidasoa River between France and Spain. The island is approximately 6,800 square meters in size and serves as a historical site where the Treaty of the Pyrenees was negotiated and signed in 1659, ending the war between France and Spain. As part of a unique tradition, the island hosts the "Fête de la République" every six months, during which French and Spanish officials meet to reaffirm their countries' friendship. The island's sovereignty alternates between France and Spain every six months as well, symbolizing the diplomatic relations between the two nations
