Polar Posts: Signy Island

Here is a postmark I saw on one of my many scans, which led me on a fun search for information on a distant place.  The postmark is from a First Day Cover, cancelled at Signy Island, British Antarctic Territory.  I wondered where this was, whether anyone was actually stationed there, whether the mail ever touched the place.  I had a lot of questions.



The British Antarctic Territory was formed on 3 March 1962, though of course Britain had earlier claims to much of the area, going back to 1908.  In philatelic terms, it formed from the Falkland Islands Dependencies and a huge wedge of Antarctica.  Signy Island would have been served at first by Falkland Islands stamps, then by the Dependency stamps overprinted for the South Orkney Islands.  These days, there is an "Antarctic Postman" who travels from Port Stanley in the Flakland Islands to the various bases.  In order to release new stamp issues, they must be carried one of the valid offices, after which they are sold at the Philatelic Bureau in Port Stanley, and through mail and online sales.[1]

First Day Covers are all carried to the appropriate office and canceled there before being returned to the Philatelic Bureau for distribution. [1]  Stamps and other items are also available at Port Lockroy  on an island just off the Antarctic Peninsula, which is the main stop for cruise ships in the territory.  "A staff of four typically process 70,000 pieces of mail sent by 18,000 visitors that arrive during the five month Antarctic cruise season." [2][3]

Wikipedia has a surprisingly long page about this tiny island, but after looking at it for a while, it's just a list of geographical names.  You can find the history of the area on the page for the South Orkney Islands.  It looks like Signy Island is the only British research station there.

The Signy Island base (Base H) was occupied from 18 March 1947 to 13 April 1996, 49 years.  Starting in 1996, it became a summer-only station with a summer staff of 8 people.  

British Antarctic Territory does have a stamp showing the base: it's Scott #336.  Interestingly, the stamp shows a postmark from the base from 1954. Here you go:

Over at the British Antarctic Survey site, here is the latest info on Signy base.

Following leads from those simple markings on stamps from almost fifty years ago, you can step into a virtual tour of the Signy Base today.  Click a building and you can click through it and move from room to room.

I don't see any stamps on any of their walls or desks, but it certainly was a fun journey.  I'm still a bit confused by the overlapping territories of South Orkney and British Antarctic Territory ... perhaps Signy Island is served from both?

Speaking of Port Lockroy, check out "The Penguin Post Office" episode of Nature (season 33, episode 8) for a classic view of life at the bottom of the world.
