What was most remarkable was the number of sessions based on re-enactment or experimental archaeology.
Activities on site included:
Drinking ale and mead brewed with historic methods
Dressing a person in armor starting with the underwear
A late medieval armor fashion show
This doesn't include discussions of activities off site.
Peak moment: watching a re-enacted trial by combat while in the next room a pick-up choir learned plainchant -- and sang it very well indeed.
