Lowell High School, on both sides of the canal.
I wonder if the plan for the Signature Bridge was on the drawing board back in 2012.
This past week, I've seen 12 large mills, numerous gate houses (not all shown above) and many canals. Unfortunately, I've taken too photos to post here. A large number of the mills have been converted into business space and housing. I used to work in one of the mills, at the Boott Mills complex twice. The first job was a part-time one for Christmas, and it was before the mill was renovated. The second job was after the renovation.
