In the 1840s and 1850s, a new wave of development took place on a strip of waterfront overlooking Dorchester Bay (Park and Mill Streets at the Harrison Square Historic District, later known as Clam Point.) Renowned architects who had contributed to one of the most significant and intact collections of Clam Point's Italianate mansards include Luther Briggs, John A. Fox, and Mary E. Noyes. By the 1890s, Clam Point gained prominence as a summer resort with the Russell House hotel as its centerpiece and the establishment of the Dorchester Yacht Club on Freeport Street.
