Back to San Diego State University (SDSU) SDSU is beautiful and Historical I am a student at San Diego State University. It is not only a beautiful campus, but it also has a lot of historical buildings. It was established in 1897, and it has a lot of spanish colonial architecture. It is also at the same time very modern, with new buildings, beautiful library, nice food court, and all the new high tech. Go and see it, you'll like it!
