Where In Ottawa XLVIII

I always look forward to Where In Ottawa, and not just because it helps me remember Roman numerals. I get to explore the city in which I live and learn new places, and new things about old places.

For those of you who are unfamiliar with Where In Ottawa, here's what you need to know. Starting today, you have only five days to solve the challenge. Actually, it's four-and-a-half days. The contest runs from 9:00 today and ends at 9:00 on Friday evening.

Here are the other rules for Where In Ottawa:

• If you think you know the location of the structure in the image, leave your guess in the Comments section of this post. Answers sent to me by Twitter, Facebook, e-mail, or any other method than by writing a guess in the Comments section do not qualify for this challenge. I will not reply to any other form of guess.
• If you were with me when I took the photo, you may not participate in the challenge.
• If you have won Where In Ottawa in the past, you may still participate.
• You may leave as many guesses as you want.
• Starting tomorrow, I will leave clues to the location in the upper-right column of this post, adding a new clue each day until the challenge is solved.
• Clues will also be accompanied by a new photo with a new view of the location. While the clues will accumulate in the right-hand column, the photos won't. Only one photo will appear each day and will replace the previous photo.
• If the challenge has not been solved by 17:00 EST on Friday, June 5, the challenge will end and I will reveal the location on Monday, June 8.
• There is no prize for winning the challenge. You only come away with a feeling of pride, having proved that you know this city.
• The winner will be announced at the first available opportunity.

Are you ready? Here's the new photo:
