Milton and Boston firefighters responded around 7:40 a.m. to what was left of the old Mattapan Paper mill on the Milton side of the Neponset behind the Price Rite.
The Boston Fire Department reports no injuries in the blaze at the former warehouse.
Mattapan Paper, which dated to a 1728 charter by the king of England, at once time covered much of the grounds on either side of the river.
After the plant shut down, a developer tore down most of the buildings on the Boston side and put up the beginnings of a new mall that now includes the supermarket and a bank.
