Spent most of my time in Jutland.
Go up the West Coast, stop at the little village churches, look in the churchyards. Lots of stones reading, "Unknown British Seaman, May, 1916" and, right next, "2 Unbekannter Deutshce Held, Juni, 1916". Battle of Jutland was May, 1916; the bodies washed ashore for 2 months afterwards. Many of the churches have Runestones, churches are MUCH older than they look. The church Towers served as local defense areas from raiders, much stronger than you would think. Many are 12th Century; the Vikings built in wood, but Denmark developed brick because they were OUT of wood by 1100. Oak grows slowly, cuts fast.
Lots of little LOCAL museums: pre-Viking grave goods and sacrifices, HUNDREDS of bent swords, tons of Neolithic tools.
I met ODIN in a little local museum, not far from Aalborg.
Aalborg (Eel-town) city defences on the hills surrounding, German BUNKERS, then there is Lindholm Hoje up overlooking the air base: Viking graveyard with ship-graves made of stones. Pour them a mug of Ale for me. Greatest Navigators in history.
Silkeborg: Vaben Sjoberg: one of Denmark's TWO gun shops, Be prepared to cry a lot; they dewat almost everything. I saw 200 brand-new Werndls, all welded.... and I can't find even a wreck in this country. Lotsa homemade Sten mags, Steilhandgranate 24 igniters, things like that.
Jelling: the two great Mounds (Hojer: highs), one for King Gorm, one for Queen Thyra, parents of King Harald Bluetooth, grandparents of King Sven Forkbeard who became King of England for 5 weeks and who was the father of King Knut Sveinsson: CANUTE of England. King Harald Bluetooth's church is still there, Bishop Poppo's tiny church (975) was discovered in the basement the summer I was there. And the Stones are there: boundary stone from King Gorm, King Harald's memorial/bragging stone proclaiming Denmark to be a Christian country: "This stone was erected by Harald in memory of Gorm his father and Thyra his mother, that same Harald who ruled all Denmark and who made the Danes Christian." I have TOUCHED it!!!!!!
King Gorm and Queen Thyra are still there, so walk quietly.
Go South, goose-step your way into Chermany for a day, go to the Schloss Gottorp Landesmuseum outside of Schleswig (Slesvig, in Dansk). Viking gold by the hundredweight, Bog People by the dozen and a SHIP exactly like the ones Hengest and Horsa used to invade Magna Brittannia in the time of Vortigern.... and changed the name to AENGLALAND (land of the Aengels).
BTW, just about anything is FORBUD. This has nothing to do with Bud from Carlyle or Bud from Canmore. Means FORBIDDEN. Stopping forbud, Svimwning forbud. Parkering forbud. Had a lot of fun with that, drove my wife halfways nuts, looking for this BUD who seemed to own the whole country.
Guards at the Royal Palaces had Garands with exhibition-grade woodwork when I was there. There seems to be a law against slugging one of the guards and stealing his rifle. No sense of sympathy for an honest Milsurp collector. And they have a round up the pipe.
And the girls. A jaw-rag to keep the flies out of your mouth is a really good idea. Some of them are just freakin' ay-maaaaaay-zing.
God rejse!
(Sounds like you will be "farting" a lot. "Fart" in Danish means TRAVEL. A town called Middlefart will be halfway between two more important towns: the middle of the journey. Distance stones by the roads in km and hundreds of metres, but the OLD ones still stand; they are in Danish Miles: 22,000 feet or close to 7km. Check out Den Gamele Haerveg: the Old Army Road: Middle Ages. In Aalborg, be SURE to see Den Gamele By: The Old Town: medieval buildings got together in the local park: utterly fantastic. Lots of towns called RUP: means a clearing in the forest. TRULY ancient names. Yes, all of Jutland was a huge Oak forest back in Year 1. It has changed a bit. And there are DOLMENS EVERYWHERE. Sorry I can't go on: fingers are sore. DO have fun!)
