A narrow winding path in the hills led up to it; cobbled floor, and high walls on either side. The slight gradient of the path was broken periodically by a series of stone steps. Suddenly, we reached a break in the wall. We got just a glimpse of the town, before our view was blocked by the trees. Five minutes passed; another break in the wall; red roofs in the distance. The next break brought with it a view of the Old Bridge and the river Neckar which it crossed.
