It's true that not all parts of the Arcadia project are written in Ada.
However, it is the primary language, or at least it was when I was there. 

I was one of the primary designers of the Arcadia user interface management
system, Chiron. It is written in a combination of Ada and C++. I chose to use
the languages which I felt worked best for the different parts of Chiron. I
didn't have to use Ada, rather I chose to use it. If Ada 9x was available
back then, Chiron would probably have been done entirely in Ada. C++ is used
within Chiron for its inheritance and classes which Ada 83 lacks.

Chiron, alone, has tens of thousands of lines of Ada. So, how hard did you
look?
