While staying at a hotel in Prague, I noticed an unlabeled black and white photo of this canal. I thought it looked magical and wanted to find it. So I took a picture of it on my phone, and used Google's "search by image" service. Worked like a charm. We finally stumbled across it in the Lesser Quarter (Malá Strana) during our early morning walk around the city, and there it was - looking even more beautiful than it did in the hotel photo. If you're planning to visit Prague at any time, my biggest piece of advice is to wake up just before dawn and explore the city's winding, cobbled streets when the tourists are still asleep. It was a magical experience.
