Early in the nineteenth century, Lowell, Massachusetts sprouted near the confluence of the Merrimack and Concord rivers.  To harness the power of the rivers, the town fathers dug a network of canals and built sprawling brick buildings. Throughout the 1800s, Lowell was home to a hive of immigrant and migrant workers.  The industry and the workers are mostly gone now, but they've left us a rich history and a landscape of bricks and water.
