However, what I see this time is most different. Although the buildings are still there, the streets remain the same, Bologna does not seem to be the original one. It may be said that what kind of scenery is determined by what kind of vision.

　　The buildings in the old town of Bologna, the side facing the street, all have tall corridors. With these, no matter what seasons, rain or snow, it'll do properly. And those pillars, because of the long time of construction, mottled or dark, reveal the depth and breadth of history. Walking under such a corridor is like walking in a historical tunnel, as if you may encounter the ancient sages at the corner of the colonnade. It is no wonder that the ancient Greece once produced a colonnade school. Such a porch is indeed suitable for discussing philosophy, where debate can be lasting forever.

　　The most amazing thing is that Bologna has one of the world's longest promenades, Portico di San Luca, which rises from the foot of the mountain to the top, just like the Great Wall of China. In the city center, the No.14 bus will take you to the sports stadium in ten minutes or so, where you can see the entrance to the promenade. Along the countless steps, you can climb to the top of the mountain in about an hour and reach the end of the promenade for a total length of nearly 4 kilometers. At the end of the promenade, also the highest point of the mountain, there is a church called Madonna di San Luca. The exit of the promenade faces the blue sky, where a cross stands, as if it was descending from the high sky. It turns out that this corridor is not a simple shelter from the wind, but also a ladder leading to the "Heaven".

　　Upon mentioning Bologna, of course, you may not miss the University of Bologna, because she is the first university across the globe as she was founded in about 1088. Her history, like a promenade, extends to the pervasiveness, where many glorious names are shining – Paracelsus, Dürer, Tasso, Erasmus, Pico Mirandola, Nicolas Copernicus etc., they were here to study or coach, and Bologna becomes an academic sacred place. That is why Bologna is called the source of L'alma Mater.

　　Today, the University of Bologna has many modern teaching facilities. However, when it was established 900 years ago, it was most shabby as her classroom was the open space in front of the church. The balcony on the church was the podium. The teacher stood there to lecture and the students listened in the open air. The first course offered here was law. It is not difficult to see the connection between the university and the church that gave birth to modern civilization: the university was nurtured by the church, and the science that overthrew the various statements in the Bible was produced in the university. This means that the enemy of the church is created by herself, and the things in the world are so complicated.
