Odense Castle (Odense Slot) ⭐ 4.1 (centre-north)
The grounds and park are open 24/7 and make for a lovely stroll, especially since it’s right next to the train station.
Tidens Samling ⭐ 4.6 (centre-west)
A hands-on museum of 20th-century Danish everyday life where you can touch, sit on, and interact with everything. A hidden gem.
