ETA: Author’s Note: All of my research on this site comes from what I can glean from books and articles, with a small amount of input from one previous research trip to Chelles. The research trip talked about here is the one I am saving for now. If you want to help send me, stop by and get a t-shirt for friends, family and two for yourself.

In anticipation of my research trip, I put together a Google map to help keep track of where I want to go. Check back to see how it grows as I add locations to my wishlist.

Enjoy your trip! I at least will look forward to hearing all about what you learn in your travels.
This is my dream research trip. Sadly, it will have to wait until I win the lottery before I can actually go. But feel free to recommend sites to add to the map! I’m looking for museums with early medieval artifacts on exhibit or available for study, living history groups, extant architecture.…. just anything, really. And if the Research Fairy Godmother waves her wee wand about and plops a pile of cash in my bank account, you can bet your bottom dollar I’ll post all sorts of pictures here!
Sigh. Me too! While I’m semi-employed no Scandinavian trips for me! (Sorry I misread your post!)
I loved my visit to Tromsø If you come that far north, drop by Luleå (Sweden) and visit too–we don’t have the lovely mountains, but we do have crash space available. (We are only 10 hours drive south of Tromsø, so quite near by, compared to getting to Europe in the first place.)
Thanks! I am really hoping to get up there someday!
Suvia: I recently blogged about the Metropolitan Museum of Art Publications available for free download on the Internet.
Today, I found a Met Publication that you may be interested in:
Brown, Katharine Reynolds, et al., eds. From Attila to Charlemagne: Arts of the Early Medieval Period in The Metropolitan Museum of Art (2000).
It has an essay about Merovingian women’s brooches and an article entitled “Aspects of Late Merovingian Costume in the Morgan Collection,” among many others. And it’s available for free download here. Enjoy!
