Skansen was one of my favorite places to visit in Stockholm. It is a living history museum with the dreamiest bakery, darling grass-roofed houses, moody cafes with peeling wallpaper and candles, arts + crafts studios and farms (with reindeer!). I am so completely charmed by it. More photos here.
P.S. I refer you to Laura Normandin's post for some really pretty photos of Skansen.
