The Wood Worsted Mill is located at South Union St. and Merrimack Street, on the south bank of the Merrimack River, in Lawrence, Massachusetts. The mill building was constructed between 1906 and 1909 for the American Woolen Company, and was dubbed by some locals as the "eighth wonder of the world" due to its size. It is a six-story brick building that is 1,300 feet (400 m) long and 125 feet (38 m) high, and encompasses some 17 miles (27 km) of aisles. Its purpose when built was to perform the complete textile manufacturing cycle of worsted woolens, from raw material to finished fabric, under a single roof.The surviving mill elements include the main building and a portion of a storehouse. The storehouse is a seven-story brick building located just east of the main building, of which approximately half remains from its original construction. The two sections (of an original four) were demolished in 2009, along with a number of other structures in the complex, including sections of the main mill building.The main mill building as it now stands is divided into four parts, featuring Romanesque Revival styling executed in brick with granite and cast stone detailing. The first is an office section, which protrudes from the main body. Like the main part of the building it is six stories, but is topped by a clock tower. The other three sections were originally labelled D, E, and F, and extend eastward from the office. Section D is 33 window bays, E is 42, and F 45 window bays in length. There are three stairwell towers that interrupt the pier-and-spandrel construction of the length of the building on its south (street-facing) elevation. These stairhouses are where entry is gained to the premises, through doorways recessed under arches. The north facade, facing the river, is uniformly window bays, broken only by wrought iron fire escapes and a few bricked-up bays where the building was connected to the demolished A, B, and C sections via covered bridges over a railroad spur.The mill complex was listed on the National Register of Historic Places on August 12, 2010. At the time of the listing, section D was being converted to residential housing.

The American Woolen Company Townhouses are a collection of brick townhouses built c. 1907 by the American Woolen Company in Lawrence, Massachusetts. They were part of a program of company-built housing between 1906 and 1910 that included the nearby American Woolen Mill Housing District. The townhouses are located on a series of short streets off Market Street in South Lawrence. A historic district comprising these six buildings was listed on the National Register of Historic Places in 2012.The townhouses stand on a large parcel of land 100 feet (30 m) deep, with 475 feet (145 m) of frontage on Market Street. The lot has been divided into three sections, each of which contains two townhouses facing each other across a central private road (Wood Way, Washington Way, and Prospect Way). The short ends of the townhouses face Market Street. When originally built the central areas provided foot access to the units, but they have been paved over and are now used for parking.The six buildings are identical in all major details, and were designed by local architect James E. Allen. Each one is a two-story brick 98 feet (30 m) long and 39 feet (12 m) deep, and houses seven living units. Each unit presents 14 feet (4.3 m) of frontage into the central area. There are minor variations in the front facades of the units. In some cases the entries of adjacent units are paired, and some entries or entry pairs are sheltered by a pilastered pediment. The rear of all units was substantially identical: a recessed porch, set under a segmented arch, provided access to the unit's back door.

The Pemberton Mill was a large factory in Lawrence, Massachusetts. It suddenly collapsed and occupants were crushed or burned alive on January 10, 1860, in what has been called "the worst industrial accident in Massachusetts history" and "one of the worst industrial calamities in American history." An estimated 88 to 145 workers were killed and 166 injured.Investigators attributed the disaster to substandard construction that was then drastically overloaded with second-floor equipment, all evident and preventable. The event was cited in improvements to industrial construction and workplace safety. The mill was soon rebuilt in place.

The complex was listed on the National Register of Historic Places in 1979, and included in the North Canal Historic District in 1984.

The North Canal Historic District of Lawrence, Massachusetts, encompasses the historic industrial heart of the city. It is centered on the North Canal and the Great Stone Dam, which provided the waterpower for its many mill complexes. The canal was listed on the National Register of Historic Places in 1975, while the district was first listed in 1984, and then expanded slightly in 2009.The city of Lawrence was founded by industrialist Abbott Lawrence and the associates of the Essex Company as a model industrial city. In 1845 they company acquired land from then towns of Methuen and Andover and began construction on the North Canal and the Great Stone Dam. The work included dredging and building out of "new land", and effectively created a small island between the Merrimack River and the canal, whose outlet is at the mouth of the Spicket River. Work on these two major features was completed in 1848, and development of the city, which formally incorporated in 1853, proceeded from there. The historic district encompasses, in addition to the canal and the dam, the mill-related buildings on the island and on the north side of the canal, as well as a few buildings that front on Methuen and Union Streets, or the connecting side streets. The 2009 expansion of the district, included a single building, the Morehouse Bakery building at 5-9 Mill Street.
