I have the habit of collecting the occasional vintage postcards, usually relevant to something I'm interested in at the moment. As a result, over the past year I've spent a fair amount of time (and a little money) collecting postcards of various tombs in Pere-Lachaise cemetery in Paris, views dating back to the late 19th or very early 20th century.
Anyway, after our recent all-too-brief trip to see and walk Hadrian's Wall -- a walk cut dramatically short by cold rain and even colder wind -- I spotted the following card online. It was taken sometime in the early part of the 20th century. The copse of trees in the distance is pretty much where the Roman fort at Housesteads is located -- and also represents the short portion of the wall that we walked, indeed it's also noted as the section of the wall that you can actually walk on top of.
