The oldest surviving wood-frame house in New Hampshire and Maine was built in 1664 by Richard Jackson, a woodworker, farmer, and mariner, on his family's 25-acre plot. At that time, timber from the region's abundant pine forests formed the basis of the economy. The extensive Piscataqua riverway powered scores of sawmills and linked the hinterlands to the sea and distant ports. Jackson's house resembles English post-medieval prototypes, but is notably American in its extravagant use of wood. Succeeding generations added a lean-to and more rooms to the east to accommodate several different family groups sharing the property at once.

The house offers tours.

For 189 years the Butler-McCook House and Garden was home to four generations of a family who participated in, witnessed, and recorded the evolution of Main Street between the American Revolution and the mid-20th century. The house's exterior looks much as it did when it was built in 1782. Behind it is a restored Victorian ornamental garden, originally laid out in 1865. Inside are the original furnishings ranging from Connecticut-crafted colonial furniture to Victorian-era toys and paintings to samurai armor acquired during a trip to Japan. The objects were accumulated over the course of more than 125 years by members of this clan, which included physicians, industrialists, missionaries, artists, globe trotters, and pioneering educators and social reformers. The Main Street History Center's keystone exhibition, "Witnesses on Main Street," uses the Butler and McCook families' words and experiences to chronicle their neighborhood's transformation from a clutch of clapboard dwellings, taverns, and artisans' shops into a modern urban enclave of multistory steel, brick, and stone structures housing major financial, industrial, governmental, and cultural institutions.

The house offers exhibits and tours.
