The first place to check in is the canteen of Heidelberg University - I want to have a college meal. It used to be a barracks, and now it is not only a barracks for students in Heidelberg, but also open to society. It is a pity that the Raiders did not do home. It was the summer, and the canteen was closed. It’s a trip to the shade of the canteen outside the canteen. The city of Heidelberg is named for its castle on the hillside of Königstuhl outside the city, and the other one that makes Heidelberg famous is Heidelberg University. Built in 1386 by the decree of Pope Urbain VI, it is not only the oldest university in Germany and one of the oldest existing universities in the world, but also a research center for cutting-edge sciences such as biomedical sciences in Germany. More than 30,000 students are now in school, nearly half of them masters and doctoral students. Heidelberg University has 27 Nobel laureates. Heidelberg's schools in the old town are mostly departments of humanities and social sciences. The summer vacation has made the neighborhood once full of youthful vitality and wisdom a quiet place.
