Where Was Caesar Stabbed?

When in Rome this past July, I was curious about where Caesar was stabbed.  Most know he was stabbed in "the Senate", but most visitors probably think that's the Curia in the Roman Forum.  Those who've delved a little more deeply into the subject know that, at the time, the Senate had been meeting in the Theater of Pompey, perhaps a 20 minute walk from the Forum.  How do I know it was 20 minutes away?  Because my hotel was right around the corner from the Largo Argentina, the only area of remains left in the vicinity of the Theater of Pompey.  It took us 20 minutes or so to walk to the Forum from there :-)

I took pictures of the signs that were there; note the mention of Caesar in the first one:

 We determined, based on this picture, that Caesar was probably murdered on the spot under the building behind the buses in this picture:

Turns out that my travel companion and I weren't the only ones interested in this, as some archeologists now think they've identified the spot.  I wonder how close I was!
