I have visited Oxford many times over the years. I also worked there for a couple of years (doing extreme commuting). Looking back, the last time I was in Oxford was in 2023. I had though in those visits never visited Brasenose College. It was founded in 1509. It is one of the many college that constitute the University of Oxford.
I was attending a conference there over two days and it certainly is a splendid building, and though I wasn’t able to explore I did enjoy walking around the various quads.
