Panama Canal Zone

The Panama Canal Zone was a 553 square mile territory inside of Panama, consisting of the Panama Canal and an area extending 5 mi (8.1 km) on each side. Its border spanned three of Panama's provinces and was created on November 18, 1903 with the signing of the Hay-Bunau-Varilla Treaty.

From 1903 to 1977 the territory was controlled by the United States of America, which was the nation that built and financed the canal's construction. From 1977 to 1999 the canal itself was under joint U.S.-Panamanian control. A 1979 treaty established the neutrality of the canal. [1]

During the American ownership, the territory, apart from the canal itself, was used mainly for military purposes. This usage ended when the zone returned to Panamanian control. It is now a tourist destination of sorts, especially for visiting cruise ships.

Postage stamps

The Canal Zone issued its own postage stamps beginning in 1904. Initially they were the current stamps of Panama or (less often) the US, overprinted with "CANAL ZONE" in various ways. Philatelists have identified over 100 varieties, some of them quite rare (and counterfeited). The last of these overprints were issued in 1939.

In 1928, the Zone issued a definitive series inscribed "CANAL ZONE POSTAGE" depicting various persons involved in the construction of the canal, as well as a 5c value showing the Gaillard Cut. A series of 16 stamps in 1939 commemorating the 25th anniversary of the canal's completion showed "before" and "after" views of various points along the canal. Thereafter stamps appeared at an average rate of about two per year, with a commemorative set in some years and no stamps in others. The inscriptions were changed to just "CANAL ZONE" in the 1960s.

The last stamp of the Zone was issued on October 25, 1978, and depicted one of the towing locomotives and a ship in a lock. Thereafter Panama resumed the administration of postal service.
