Walpurgis (sv. valborg) is perhaps the highlight of the social calendar in Uppsala. The Swedish-language Wikipedia has an entire sub-article on the events of the day, which I’ll copy here and amend with my own annotations:
07.00-09.30 Champagne Breakfast on Castle Hill: Yes, most people are drunk by 7 am. Skipped this.
10.00-12.00 Waterfall Rafting on Fyrisån
The idea here is that student clubs build makeshift rafts and dress up according to a chosen theme (mimes, squid, clowns, etc). They float down the Fyris river and, at the sharp drop by the old mill, go over the waterfall. This usually means the end of of the rafts, but they’re judged on style at the precise moment they rush over the edge, wading out after they come out of the water downriver.
12.00-14.30 Herring Picnic Lunch: Nothing like pickled fish on top of the champagne from breakfast. Skipped in favor of less-traditional pasta.
15.00 Rector magnificus bids welcome to Spring from the balcony of the library by lifting his student cap, signaling great celebration and consequent stampede down Carolina Hill to the Champagne Gallop at various student clubs.
Anders Hallberg, the rector, steps out on the balcony:
…and puts on his hat, the “Mösspåtagning” which signals the arrival of spring:
I stayed for the hat-waving but skipped any and all galloping. An interesting part of Valborg is how it functions as a kind of Alumni Reunion weekend, with older folks who once attended Uppsala blending in with the rest of the student body:
21.00 Curator curatorum (Student Body President) gives Spring Speech on top of Castle Hill, followed by a concert given by Allmänna Sången.
This I did attend, which proved to be quite atmospheric. Representatives of all the Student Nations had their respective flags and banners fluttering atop the hill next to the castle at sunset, while 420-year-old Gunilla bell was rung. The renowned choir Allmänna Sången sang while attired in evening gowns and tuxedos. The tradition of student choirs in Uppsala dates back to the early 19th century, and like many other things in Swedish academic arose under the influence of Germans who came northwards to work. Swedish Radio broadcasted the talk and the concert live from the top of the hill.
