The stamp issued by Chile in 1968 commemorates centenaries of five towns on the island of Chiloé with a map: Chonchi (1768), Tenaun (1567), Castro (1567), Chacao (1568) and Ancud (1768). At the top of the stamp part of the province of Llanquihue is delineated and the town of Pargua is located. Llanquihue was absorbed by the island province of  Chiloé in 1928. At the bottom of the stamp a portion of Chiloé is delineated and the towns of Ancud and Chacao are located. A ferry connects Pargua and Chacao.
     The map shows an area about two-thirds of the way south in Chile on the Pacific coast.
