Richman Margeson Estate

Great Bay National Wildlife Refuge was established in 1992 and is located along the eastern shore of New Hampshire's Great Bay in the town of Newington. The area was formerly part of a weapons storage area at Pease Air Force Base, which was closed in 1991. A variety of rich wildlife habitats from uplands to open waters can be found throughout the refuge. Both Great Bay National Wildlife Refuge, and the Karner Blue butterfly easement in Concord, New Hampshire, which protects important habitat for this federally endangered species, are managed by the Parker River National Wildlife Refuge in Newburyport, Massachusetts. The refuge has a surface area of 1,116 acres (4.52 km2).

Great Bay is a tidal estuary located in Strafford and Rockingham counties in eastern New Hampshire, United States. The bay occupies over 6,000 acres (24 km2), not including its several tidal river tributaries. Its outlet is at Hilton Point in Dover, New Hampshire, where waters from the bay flow into the Piscataqua River, thence proceeding southeast to the Atlantic Ocean near Portsmouth. The northern end of the bay, near its outlet, is referred to as Little Bay.

The Newington Center Historic District encompasses the historic civic heart of Newington, New Hampshire. It consists of a section of Nimble Hill Road between its junction with Little Bay Road, and a gate at the southern end marking the start of territory formerly associated with Pease Air Force Base (now Portsmouth International Airport at Pease). This area includes the town common, laid out in 1640, a cluster of civic buildings, and several private residences, as well as remnants of the state's oldest town forest. The district was listed on the National Register of Historic Places in 1987; in 1991 an additional 69 acres (28 ha) of former town forest, now part of the airfield, were added to the district.

Portsmouth International Airport at Pease (IATA: PSM, ICAO: KPSM, FAA LID: PSM), formerly known as Pease International Airport, is a joint civil and military use airport located one nautical mile (2 km) west of the central business district of Portsmouth, a city in Rockingham County, New Hampshire, United States. It is owned by the Pease Development Authority. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a non-hub primary commercial service facility.The airport is located within the Pease International Tradeport, a result of the ongoing redevelopment of the former Pease Air Force Base which was closed under Base Realignment and Closure (BRAC) Commission action in the late 1980s and early 1990s.

Pease Air National Guard Base is a New Hampshire Air National Guard base located at Portsmouth International Airport at Pease in New Hampshire. It occupies a portion of what was once Pease Air Force Base, a former Strategic Air Command facility with a base-related population of 10,000 and which was home to the 509th Bomb Wing (509 BW) flying the General Dynamics FB-111A. Pease AFB was closed pursuant to 1991 Base Realignment and Closure Commission action, with the 509 BW transferring to Whiteman AFB, Missouri. In 1983, investigations had shown soil and water contamination with degreasers and JP-4 jet fuel, and in 1990 the base was put on the National Priorities List of superfund sites. As of 2015, after 25 years of the Pease Development Authority's work, Pease International Tradeport has 275 businesses employing close to 10,000 civilian workers. Pease continues to be home to the New Hampshire Air National Guard's 157th Air Refueling Wing (157 ARW), an Air Mobility Command gained Air National Guard unit, and since 2009 the 64th Air Refueling Squadron, an active duty United States Air Force "associate" unit to the 157th. The 157 ARW was a former tenant activity at Pease AFB and remained at the installation following the BRAC-directed closure of its regular Air Force activities. As of 2011, the base population is 380 full-time military personnel, with a monthly surge of up to 950 when part-time military personnel are included.

The Winnicut River is a 9.1-mile-long (14.6 km) river in the Seacoast region of New Hampshire in the United States. A small river, it is nonetheless the major southeastern tributary of Great Bay, an estuary connected by way of the tidal Piscataqua River to the Atlantic Ocean. The Winnicut River rises at the northern outlet of Line Swamp in the town of North Hampton, New Hampshire, just west of Interstate 95. The river flows north through gently rolling fields and scattered suburban development, eventually entering the town of Greenland. It passes under New Hampshire Route 33 and becomes a tidal river for its remaining mile to Great Bay.

The Oyster River is a 17-mile-long (27 km) river in Strafford County, southeastern New Hampshire, United States. It rises in Barrington, flows southeast to Lee, then east-southeast in a serpentine course past Durham to meet the entrance of Great Bay into Little Bay. The bays are tidal inlets of the Atlantic Ocean, to which they are connected by a tidal estuary, the Piscataqua River. The freshwater portion of the river is 14.1 miles (22.7 km) long, and the tidal river extends 2.9 miles (4.7 km) from Durham to Great Bay.The Oyster River reaches tidewater at the base of a dam in the center of Durham, just west of the river's crossing by NH Route 108. Due to siltation, the river is only fully accessible to motorized boats west of the Durham Water Plant for approximately three hours on either side of high tide. Boaters have noticed the increasing effect of siltation on navigation since 1998.

The Weeks House, also known as the Old Brick House, is a historic house museum on Weeks Avenue in Greenland, New Hampshire. Built about 1710, it is one of the oldest brick buildings in New England. It was built by an early colonial member of New Hampshire's politically prominent Weeks family, and is now maintained by a family association. The house was listed on the National Register of Historic Places in 1975.

The Great Bay National Estuarine Research Reserve encompasses a diversity of land and water areas around Great Bay, an estuary in southeastern New Hampshire. Protected lands cover 10,235 acres (4,142 ha), including approximately 7,300 acres (3,000 ha) of open water and wetlands that include salt marshes, rocky shores, bluffs, woodlands, open fields, and riverine systems and tidal waters. Great Bay has a rich cultural history and was the first major commercial waterway developed by the early settlers. The National Estuarine Research Reserve System (NERRS) is a nationwide network of state-owned and -managed coastal protected areas. These are designated and supported by the National Oceanic and Atmospheric Administration (NOAA) under the United States Department of Commerce. The New Hampshire Fish and Game Department under the Marine Fisheries Division manages the Great Bay NERR. Designated in 1989, the reserve's primary purpose is to promote the wise use and management of the Great Bay estuary.

The Squamscott River is a 6-mile-long (10 km) tidal river in southeastern New Hampshire, in the United States, fed by the Exeter River. The first 33 miles (53 km) of freshwater river from Chester to downtown Exeter is known as the Exeter River, and the subsequent 9 miles (14 km) of saltwater from downtown Exeter to the Great Bay tidal estuary is known as the Squamscott River.The combined Exeter-Squamscott watershed is 81,726 acres (127.697 sq mi) and contains 68,245 people. It includes portions of Chester, Raymond, Fremont, Danville, Kingston, East Kingston, Sandown, Kensington, Brentwood, Exeter, Newfields, and Stratham.

The Bellamy River, in Strafford County, southeastern New Hampshire, is a tributary of the Piscataqua River about 15 miles (24 km) long. It rises in Swains Lake in Barrington, 9 miles (14 km) west of Dover. It flows east through the Bellamy Reservoir in Madbury and through Dover, then southeast as a tidal river to Little Bay, the channel connecting Great Bay with the Atlantic Ocean. The river at one time provided water for swimming behind a dam at Bellamy Park in Dover. This park was a favorite spot for local neighborhood children and young adults, but fell into disrepair in the late 1960s. The Dover High School class of 1976 held a school-approved burning of the remains of the dam as a class activity. A short distance down the river from the park is the location of a former mill building, abandoned in the mid-20th century. The river helped power machinery in the mill. Further along is the final dam, at the site of the former Sawyer Woolen Mills, a large manufacturer in Dover during the late 19th century and early 20th century. The river supplied the power to this large factory. Beyond this dam the Bellamy River assumes its tidal nature, reverting to a small trickle at low tide.
