Sweden has countless castles (or 'slott' in Swedish) from its storied history. Seeing all of them would take ages. I have compiled a list of some of my favorite castles from across Sweden including Uppsala Castle, Kalmar Castle, Kärnan, Borgholms Castle, Gripsholm Castle, Vaxholm Fortress, Örebro Castle, Skokloster Castle, and Carlstens Fästning.

Uppsala is just 40 minutes north of Stockholm by train. It's the fourth largest city in Sweden (with a paltry 200k for population). Make no mistake, this charming city has great importance in Sweden as a whole. While here, you can enjoy Uppsala Castle and Linnaeum nearby. The best place in the city to experience the sunset and Uppsala Cathedral is right along the canal at Gotlandsparken.
