A public holiday on the island of St. Martin in the West Indies, Concordia Day commemorates the 1648 agreement to divide the island between the Dutch and the French. To this day, St. Martin is the smallest territory shared by two sovereign states, with only a stone monument marking the boundary. Concordia Day celebrates the long-standing peaceful coexistence of the two countries by holding parades and a joint ceremony with French and Dutch officials at the border monument. November 11 is also the anniversary of the island’s discovery in 1493 by Christopher Columbus. Discuss
