Given that Paris is riddled with covered passages, and stunningly beautiful ones at that, the Passage des Princes is admittedly not one of the prettiest. Built in 1860, but destroyed only 25 years later, it wasn’t restored to its original glory until 1995. It does have a lovely tiled floor, and a superb glass dome ceiling as well as a little courtyard for a short respite, but that’s not usually the reason visitors come here. It’s generally because the entire passage is practically one big toy store.
