Caesar was killed in the Theatre of Pompey, which was not, I believe, in the forum.
True, there were repairs underway at the Forum at that time. Thanks for encouraging me to check the story out. I truly appreciate how this course with the orators on the audio and the insightful student comments have given me a fresh perspective of Ancient Rome. I'm seeing it all much more sharply now with my schoolboy views of 60 years ago given improved accuracy and maturity.
