One of the reasons I enjoy your photographs is that I have a friend in Flanders. We've toured the area and visited some of what you have documented.
Not the best of my photos, but they're online and they're some of my favorite, so here they are.
A hundred years later they still maintain these sites like they are new. In the summer they're green with grass, flowers and in some places people will even leave a little something at the memorial. A picture of a great grandfather with flower or something. They still blow the Last Post at the Menin gate in Ypres every night for 90 of the last 95 years. Places like Tyne Cot are beautiful, sad, and remarkably moving.
For centuries, Belgium was where Europe went to fight their wars. The folks in Flanders got the worst of WWI and wanted people to never forget.
