The rue de Siam (or Siam Street) is the main arterial street of Brest. Its name comes from the arrival of three ambassadors led by Kosa Pan, sent by the King of Siam on the 29 June 1686 to meet Louis XIV in Versailles. They went with six mandarins, three translators, two secretaries and a retinue of servants, loaded with presents. They traveled on the boats l'Oiseau and La Maligne.
