About Seabrook NH

Seabrook NH rests at New Hampshire’s southern coastal edge roughly 43 miles north of Boston MA. Settled in 1638 and named for the many brooks flowing through extensive salt marshes to the Atlantic, this community has always embraced its coastal identity. Early settlers engaged in farming, fishing and clamming—industries that shaped Seabrook’s character for generations. The town once comprised six distinct villages: Crowtown, Seabrook Village, Smithtown, The Depot, South Seabrook and Seabrook Beach.

The iconic Old Man of Seabrook watched over Route 1 for decades—a beloved tin-and-iron landmark that became a fixture for countless travelers. Brown’s Lobster Pound, operating since 1948, remains a cherished destination where diners enjoy fresh catches with Atlantic views. The Historic Chain Bridge and Old South Meeting House connect residents to their heritage. Today’s Seabrook balances its fishing village roots with modern development along Route 1. Seabrook Beach offers quieter coastal living compared to busier neighboring beaches. Housing ranges from historic Federalist and Colonial homes to contemporary beach cottages. This gateway community values its small-town atmosphere, working harbor and special connection to the sea.
