The National Museum. Plenty to see and do!
Permanent exhibitions include Danish prehistory, middle ages and renaissance. The children's museum is more like a playground with viking ships and medieval castles.
You are welcome to bring your own food and eat in the museum's dining room, or eat at the popular Restaurant Julian which is famed for its excellent climate-friendly weekend brunch (do book a table in advance!). Julian also sells lunch packs to go.
The museum has a giftshop, but if you have a special interest in prehistory jewellery I would recommend a visit to Museums Kopi Smykker in Grønnegade.
Note! Free admission - however, you are not permitted to bring large rucksacks and if you want to leave your rucksack or coat in the wardrobe you will need a 10 kroner coin to use a locker. Free guided tours in English at 11 on Tuesdays, Thursdays and Sundays in June, July, August, September. Photography permitted.
