Luxemburg - A Really small place

Train from Paris to Luxemburg early in the morning after just a few hours sleep. This backpacking life starts to get a little annoying when you have to drag the stuff with you everywhere. 2-3 days in each town and then on the road again. I only had a few hours to spend in Luxemburg because the train to Berlin left earlier than expected. There is a place in downtown called the Kircheberg which is a hill with a big cathedral where the Luxemburg people had their fortress. For combat purposes a long time ago this place is perfect, there is a deep valley surrounding the place and there is NO WAY anyone could make it up here while some archers are shooting down. The train from Luxemburg to Berlin lasts for 9 hours, it's a long and booooring ride.
