Roman Numerals

[RobertKB]

Definitely off topic. I learned Roman Numerals when I was a kid. My grandsons have no idea. Not much used today except maybe on some clocks and for the Super Bowl. It’s time my grandsons, 15 and 13, knew so I am going to teach them. Roman Numerals are really pretty straight forward once you know the seven letters involved and how they’re placed. 
 

Picture below has Roman Numerals on a well-known building, at least to me. 
Questions:

1. What’s the date?

2. What city is it in?

3. What is the building?

 

If you have travelled much, many of you will have seen the building. One clue, it’s not in Rome.

Congratulations! Date is correct.

One year off.  I missed the "I".

Yes, the “I” is not quite as obvious as the other numerals.
