I was here yesterday as well. This is the site of one of the bloodiest battles ever, not only in Sweden, but in Europe. Thousands and thousands of Danes and Swedes completely slaughtered each other here.
War sucks, but if anyone is interested I found a thing about it in English on Wikipedia.
This monument was raised 200 years later, and the inscriptions on the sides are in some kind of weird olden Danish, but I can still understand it enough to translate it I think.
The first one says:
The 4th of December
Here fought and bled
People of the same tribe
Raised the memorial
The second one says, in some attempt at rhyme:
Here lie brave men
Whose bones and blood are blended
So that no one can say other
Than that they are of one family
They were of one faith
Still, with peace
They could not together live
Or something. This editor thing double spaces things when they aren´t supposed to be double spaced, but whatever.
