We recently visited a warehouse in West Roxbury that's home to Boston's City Archaeology Lab, and the domain of Joe Bagley, the city's archaeologist.

He walked us past boxes of recovered artifacts from beneath the streets of Boston. Their labels say things like "Paul Revere's home," "Fanueil Hall, "the African Meeting House." All of them filled with 1 million artifacts that represent over 7,000 years of history.

Joe Bagley's out with a new book titled "A History Of Boston In 50 Artifacts."

Check out some of the artifacts Bagley showed us on our visit to his lab:
