That's right, Luxembourg. The photo is taken from the garden leading up to the top of the Pfaffenthal Lift. If you have not ridden that lift, try is next time you're in Luxembourg. If is a very well done piece of public transportation , connecting the lower and upper parts of the city with style and efficiency. The gold dome structure in the photo is at 49.615195N 6.129112E and can be seen on Google Maps. @newbluesea, you're up next.
