About this map

Prudence Island and the northern reaches of Conanicut Island sit at the center of this Narragansett Bay study, which details the shoreline and interior of Middletown, Portsmouth, and Newport. The landscape is a mix of agricultural plots, residential expansion, and significant military infrastructure. Massive U.S. Naval Reservations dominate the coastal margins of Aquidneck Island, reflecting the era's heavy defense presence around Coddington Cove and Melville.

Researchers will find a wealth of local landmarks, from the St Columbas Cemetery and Holy Cross Ch to family-named landmarks like Barker and Lehigh Hill. The transition from rail to road is evident as the Penn Central tracks parallel West Main Road, while the recently constructed Newport Bridge links the islands. Interior water management is visible through the Lawton Valley Reservoir and Sisson Pond, supporting the growing population centers at South Portsmouth and Two Mile Corner.
