Yesterday was the first day of springtime...but it was quite cold. I had a walk downtown...only few hours before coming back home, turning on the radiators e finish my book (after eating too mutch of my chocolate cake).
Bologna is an old town, it was already village in the VIIIth century BC, here was born the first European University, in the middle age it was one of he most important, and biggest, town in Europe.
Yesterday in a courtyard of an old palace I saw some remains of one of the first wall made by christal chalk (as you can see in the picture). It was build just out of one of the romain street that surrounded the village.
