The Newmarket Industrial and Commercial Historic District encompasses the heart of a distinctive 19th century mill town, Newmarket, New Hampshire. Its mill complex is regionally distinctive for its extensive use of stone from an early date, and the town is relatively well-preserved due to a significant economic decline after the mills closed in 1920. The district was listed on the National Register of Historic Places in 1980. The Stone School, listed in 1978, is a contributing resource.

The Stone School is a historic school building at 1 Granite Street in Newmarket, New Hampshire. Built in 1841-42, it served the town as a school until 1966, and is a distinctive example of the town's stone architecture. It is now the Stone School Museum, a local history museum. The building was listed on the National Register of Historic Places in 1978.

The Stone Church is a live music venue in Newmarket, New Hampshire. In operation since 1970, the Stone Church offers local food, a handpicked selection of local and craft beers, and local musical performances, along with national touring acts. The venue is located at 5 Granite Street, atop Zion Hill in Newmarket. It features parking for visitors and an electric vehicle charging station.The Church has had a rather eclectic past, even during its days as a church for Newmarket's mill workers, when the town housed a mill that at one time held more looms in its gigantic factory than any other building in the world. Built in 1832, the church first served as a Universalist meeting house, then 20 years later as a Unitarian meeting house. The Catholics bought the church in 1865, retaining ownership until approximately the turn of the 20th century when they sold it. The church then acted alternately as a VFW hall, a roller-skating rink, and a shoe-assembly plant, the Newmarket Heel Company, which suffered a major fire in 1968. In 1970, two former University of New Hampshire students (Rod Philbrick and John Williamson) and a third person, not at UNH (Arnet Taylor), purchased the burnt-out church and turned it into a venue for live music. From then on, the Stone Church served as a home for local musicians and touring acts such as Phish, Aerosmith, Bonnie Raitt, Parliament, Patty Larkin, Béla Fleck, David Grisman Quintet, Joan Osborne, Dirty Dozen Brass Band, The Radiators, Guster, moe., John Butler Trio, John Scofield, Soulive, Grace Potter and the Nocturnals, and local acts such as Percy Hill, Say Zuzu, Scissorfight, Thanks to Gravity, Bill Morrissey, and Truffle.

The Center for Coastal & Ocean Mapping (CCOM) / NOAA-UNH Joint Hydrographic Center (JHC) was founded in 2000 by Dr. Larry Mayer to find ways to process the massive amounts of data coming from sonar systems at rates commensurate with data collection; that is, to make the data ready for chart production as rapidly as the data could be collected.The main objective of the CCOM/JHC is to enhance methods for ocean mapping and hydrology, with the target to also advance the knowledge of the discipline's future generation. This objective underlies the aim of the JHC and its cooperative partnerships with the University of New Hampshire and the National Oceanic and Atmospheric Administration to create a national center for expertise in ocean mapping and hydrographic sciences.The center is located in the Chase Ocean Engineering building on the campus of the University of New Hampshire in Durham, New Hampshire, United States. The center works on a wide range of marine research topics, including: Hydrography Improved bathymetric processing Improved side-scan sonar and backscatter processing Data visualization, with emphasis on whale tracking, flow visualization, and mid-water fish Seafloor characterization Lidar Photographic mosaic Law of the Sea mapping for the United States Electronic chart of the future and the marine Automatic Identification System Acoustic positioning and tracking
