My great uncle Percy drew a lot during the World War I - mostly churches. One drawing was titled "Tourettes" but for years no-one knew where it was or if it was a real town. We couldn't find it anywhere near the battlefields and it wasn't until Google Maps came along that I was able to search and find a little town in the very south-east corner of France with Google Streetview revealing the church. This was only about 2 years ago.
I was thrilled to have finally solved the mystery but it spawned another mystery. As far as we know, Percy was never in the south of France. Did he draw it from a photo or postcard? Did he draw it during the war or when he returned in 1958?
The final mystery is why the image of the church is mirrored in Percy's drawing.
Tourrettes was indeed a charming little town and although it has the potential to become a "disneyland", it hasn't yet gone down that path.
Anyway, I had it marked down as a must-visit place and today I achieved it - albeit going 100kms out of my way to do it.
