A well-produced, cleanly-edited, multi-media online production on 
archaeology is found at the link below ... by Ann Gibbons, a writer for 
Science magazine, it won SAA's Gene S. Stuart award for archaeology 
writing this year. It's topic is a 11th-19th century church/monastery 
site alongside the pilgrim's path that wended its way through Tuscany 
all the way from the Pope's palace in Rome to the cathedral in 
Canterbury, England, transporting not only the pilgrims that trod along 
it, but the pathogens they were infected with. A major adjunct to the 
archaeological research has been DNA recovery from pathogens from the 
human remains buried continually over a 1,000 year period in graves 
surrounding this still standing church.

Presented in four brief "chapters" (pages) and three (brief & 
interesting) videos, it's a highly informative and recommended 
read/watch quarter-hour archaeo-edu-tainment experience:
