Entrance to the Old Athenaeum

The extra photo shows the name Athenaeum more clearly above the door.
I was surprised to learn when I looked up the Internet that it was a College for Commerce and a few other Subjects.

It wasn't until 1890 that it was partly a Music School while other parts of the Building were still being used for other Subjects.
I know that the Glasgow School of Dramatic Arts was formed.in 1950. The name became the Royal Academy of Music and Drama in 1968.

I don't know when the other Subjects were dropped as part of the College.

Of course they moved out of that Building into the new one about the 1980's. I think.
