This burg northwest of bustling Portsmouth and south of the college town of Durham is something of a hidden gem, known more for its New Hampshire mill history than for the eclectic mix of music, dining, and distinctive shopping options it offers. Newmarket has found ways to blend its past with its updated present. A stroll on Main Street, along the Lamprey River, will take you past old mills that have been turned into a vibrant and inviting blend of shops, restaurants, and condominiums, emblematic of the town’s transformation and revitalization.
