Due to Covid-19, the Cohasset Historical Society

museums are currently closed to the public. 



Designed in 1903 by Edward Nichols, a Cohasset native, and Boston architect, the Pratt Building consolidated the private Paul Pratt Memorial Library and the town's Cohasset Free Public Library. The walls of the rotunda are noteworthy for the four large murals painted by prominent Cohasset artist MacIvor Reddie. The murals depict scenes from Captain John Smith's arrival in Cohasset in 1614 through the 1850s when  Cohasset's maritime industry was at its peak.

Now housing the Society's extensive archives, library, historic costumes and textiles, and other collections, the

Pratt Building is located at 106 South Main Street.

During normal times, we are open to the public year-round, Monday-Friday, 10:00 AM to 4:00 PM for exhibits, lectures, programs, and research facilities.  We look forward to welcoming you back soon.
