At last I get to see what it is like to be in a city surrounded by its old protective walls. (These walls were completed in 1452.)
The photo on the left is of the entrance I used most of the time when entering and leaving the old original part of the city since I stayed in a small pension outside of these walls not far from the train station.
The photo on the right is a typical view of what the walls look like from inside the old city. The square towers each had a door which provided access to the top of the wall. Here it was easy to imagine men patrolling the covered walkways and keeping a close watch on any activity outside these walls.
