Just about five minutes into the countryside around Västerås, there is an ancient Viking burial site. It's called "Annundshög" and there are a bunch of old Swedish kings buried there... The graves are all set up to form the shape of Viking longboats (as can be seen above), but one king was buried and then covered with a huge mound of dirt. This king must have been special to have so much dirt piled on top of him (kind of ironic) and it's pretty awesome to look at today.
There's really something special about standing on such an ancient site... It kind of makes me feel small in the entire scope of history.
