Sadly I can't be in Cambridge today, but I wish I could - this talk by one of the Prospectors Craig Cessford looks fantastic!
"At a seminar today (22 October 2014) archaeologist Craig Cessford will talk about the challenges of working on â€˜clearance depositsâ€™. He will use, as one of his examples, the recent excavation of a site in historic Cambridge that yielded a cache of teapots, and other items, that had lain undisturbed for more than 200 years. - See more here."
"While coffeehouses have attracted significant attention from historians, relatively little attention has been paid to the material culture associated with them â€“ and very few have been investigated archaeologically."
