Boston — Boston’s famed Old North Church is the latest site of an archaeological survey designed to get a better sense of daily life going back to the city’s colonial past.

The City of Boston’s Archaeology Program led the two-week survey, which continued through Friday.

The dig explored the buildings’ backyards and privies, or outhouses, which can be critical to discovering historical artifacts.

The church’s steeple played a pivotal role in the American Revolution when lanterns were hung to signal the approach of the British, giving rise to the phrase: “One if by land, and two if by sea.”

More than 40,000 artifacts dating back 300 years were recovered during a 2013 survey near the church.
