The abandoned mill on Stevens St. just outside of Lafayette Square in Haverhill caught fire on Sunday evening around 5 p.m.
The mill had long been vacant and plans for redevelopment were under way. No injuries were reported.
Emergency vehicles closed the entire square off beginning at about 6:15 pm. Crews from many surrounding towns responded to the eight-alarm blaze.
On Monday, many NECC students mentioned being redirected in traffic and seeing the smoke from miles away all Sunday night.
Residents in the surrounding area lost power for several hours beginning at 7 pm.
Firefighters were still on the scene Monday morning and were expected to remain through Monday and even into Tuesday, if needed, to ensure that the fire cannot flare up again.
Neighboring homes were evacuated amid claims that the siding on the fire side was “melting” according to one spectator.
More pictures and information will be posted on the website as it becomes available.
