This is from an interview text:
我从小就喜欢文学， As a child I always liked literature

They are very important there??

These subjects have great weight there??
These subjects are profoundly important there??

历史的厚重感却随处可见 laden with history
So maybe I can translate:
I feel it, the university, is laden with literature, history and philosophy
I feel it is laden with them. I feel they ooze from the walls.
