At the corner of Merrimack and Dutton Streets, on the site of the modern gas station there was once a grand hotel called the Merrimack House, which opened in 1836. Similar to Mechanics Hall, this hotel was also home to several small businesses.
Starting in the 1830s, Walker Lewis (1798-1856) operated a barbershop in the Merrimack House. When he moved to Lowell in the 1820s, Lewis was already an ardent abolitionist. He was a founding member of the Massachusetts General Colored Association (MGCA).
