Being old is not something valorated nowadays in our society. However, the oldest Spanish university, the university of Salamanca (USAL), can show you that experience is something valuable and it goes together with the quality.
It has a medium size with 9 teaching campuses, located in different cities. The strongest point is the faculty of Humanities, with very a huge list of courses.
At this university study people from all around the world, you can discover new cultures, there are thematic cultural weeks (mmm…I still remember amazing sushi made by some Japanese girls), many conferences about all kinds of topics and very active students´ night life 🙂
I highly recommend it, the quality of studies and teachers´knowledge is awesome, and you will never be bored in this city full of life.
