FC1Z3U5: Some Puzzling Roman Columns

We've had an easy couple weeks. I think it's time to turn up the heat a little bit and tackle one that's a bit tougher. There are still plenty of clues to be found, but I expect it might give you more of a workout than the last few. But we can take it after the last few days of chocolate and ham, right?

This week's puzzle was written by Jennifer Kidder of the Geocaching Puzzle Of The Day Blog.

If you need a closer look at that cipher text, here it is: --C--IXXDIXCVIXXIIXVCILDXIC-IV

The checksum for this puzzle is 52. (Remember, the checksum is the result of adding all the individual digits of the coords.)

At the end you should discover a thematically appropriate item. This one is best viewed on Street View.

Please don't spoil the answer in the comments! Hints published tomorrow, and the answer on Wednesday.

Happy Puzzling!
