This church is built into the hillside on which it perches. One of the reasons the Grand Duchy of Luxembourg has survived as an independent state for a thousand years against such powerful neighbors as Germany and France, is that the area is eminently fortifiable. Even in the capitol, the gorges are deep and difficult to pass, with only a few bridges spanning the distance high above. It's easily one of the most dramatically sited capitols in Europe.
If I were to have made a list of all the countries on Earth, in the order in which I expected to see them, Luxembourg would have easily been near the bottom. It's funny where you end up sometimes. February 2006.
