This weekend's clue

Wow! This weekend has been so busy. I almost forgot to post a clue. Sorry.
Here you go: The name of the capital city begins with an "R".

And for those of you who haven't been planning along. What this is about is...
I will soon be traveling outside North American (for the first time). Though a series of clues I am hoping that you can guess the country.
Good luck
Have fun
