Construction crews were working on an expansion to the Metrolink in the city center where they discovered the burial site that is believed to be from the 18th century, according to reports.
The final count of how many were buried there has yet to be confirmed. Archeologists covered the area with a tent and studied the remains.
“This is the most amazing piece of history,” Manchester City Council spokesperson Pat Karney told Manchester Evening News.
"The fact that twice the number of bodies had to be taken out just shows how historically important it is -- as well as explaining the complications of putting a new tram line into the city center.”
The local chapel, Cross Street Chapel, will hold a service sometime next year to reinter the bodies and remains that were found.
