360 Merrimac Street offers a rare blend of depth, character, and setting along one of Newburyport’s earliest land corridors. The property follows the historic alignment known as the Old Road, creating a deep, private parcel with mature trees and a grounded sense of place. Steps from Ashland Street Landing — the former shipyard where the clipper Dreadnought was built in 1853 — the location carries quiet continuity within the maritime district. Inside, the home offers three finished levels, warm natural light, and a traditional first-floor layout with a water closet off the kitchen. The second floor includes multiple bedrooms, a full bath, and laundry hookups, while the third-floor skylit landing provides flexible bonus space. Outside, the screened porch, breezeway, detached garage, and private backyard connect to the property’s historic lines. Long held by the same generational owners, it offers opportunities for preservation or thoughtful updating.
