Greeley Park is a public park in Nashua, New Hampshire, United States, occupying 125 acres (51 ha) extending from the Merrimack River, across Concord Street, to Manchester Street. The property was originally bought in 1801 by Joseph Greeley, who passed it on to his son after his death. The land was deeded to the city of Nashua in 1896 by Joseph Thornton Greeley, the grandson of the original Joseph Greeley. In 1908, John E. Cotton donated $5000, an amount that was "matched by city funds", to change the Greeley Farm into a public park. The money was used to create a "stone and cement rest house, a fountain, a shallow pond, a gravel walk, and flower beds". Greeley Park hosts many citywide events, such as the Fairy Tale Festival, Art Show, and Halloween "Fright Night", and is a traditional photogenic place for prom night for Nashua High School South and North. On a smaller scale, at the bandstand in the spring and summer there are plays, movies and music festivals. The park also features hiking trails, horseshoe pits, ball fields, tennis courts, a community gardening section, and the only boat ramp on the west side of the Merrimack River between the Massachusetts border and the first rapids in New Hampshire. At the northern boundary of the park, near the river, the park is dealing with the threat of creosote contamination that flows from the closed nearby historic railroad tie plant.During September 1999, American politician John McCain officially announced his candidacy for president of the United States to a crowd of around one thousand in Greeley Park, beginning his first presidential campaign.During June 2020, Black Lives Matter hosted a vigil for George Floyd that was attended by over 1,000 people

The Signer's House and Matthew Thornton Cemetery are a pair of historic properties in Merrimack, New Hampshire, United States. It consists of a house, once owned by Matthew Thornton, a signer of the United States Declaration of Independence, and the adjacent cemetery in which he is buried. The house is a two-story Georgian style double house, and is the only surviving house of the period in Merrimack. It was owned by Thornton from 1780 to 1797, when he sold it to his son James. The cemetery, located across the Daniel Webster Highway from the house, is also Merrimack's first cemetery, with the oldest gravestone marked 1742.The house was listed on the National Register of Historic Places in 1978. It is now occupied by the Common Man restaurant. According to surviving archival documents, the area was formerly known as Lutwyche's Ferry, and the building currently called the Signer's House was in fact built by Matthew Thornton's son Matthew Jr. on the previous location of a farm purchased by Matthew Thornton in 1780 from William Spooner. The previous owner Spooner had obtained the farm and ferry titles somehow from the town, which had seized the property from Col. Edward Goldstone Lutwyche who had obtained ferry rights in 1767. He was a colonel of the Fifth Provincial regiment and a Loyalist. He refused an order to call out his regiment for the battles of Lexington and Concord, and on the night of April 20, 1775, left Merrimack for Boston within the British lines, leaving ownership to his mother Sarah, who remained. Sarah appealed for and was granted restoration of the ferry rights on October 24, 1775, and held them until her death September 7, 1778, aged 77 years. She is buried in Thornton cemetery. On April 14, 1784, records show Thornton needed to petition for reinstatement of ferry rights which again had been confiscated by the town upon the occasion of Sarah's death. He was successful and sold the rights in 1797 to his son Matthew Jr.

The Souhegan River is a tributary of the Merrimack River in the northeastern United States. It is 33.8 miles (54.4 km) long, with a drainage area of 171 sq mi (440 km2), and flows north and east through southern New Hampshire to the Merrimack River. The river begins in New Ipswich, New Hampshire, at the junction of the river's South Branch and West Branch. Flowing northeast, it passes through the center of Greenville and descends through a narrow valley to Wilton, where it turns east. The river valley broadens below Wilton, and the river passes through the center of Milford, crosses the southern portion of Amherst, and enters the town of Merrimack. Shortly upstream of the town center, the river passes over Wildcat Falls, then crosses under the Everett Turnpike and U.S. Route 3 to reach the Merrimack River. The river is used for water supplies, a small amount of hydropower, and recreation. There are 28 threatened or endangered species sharing the watershed with 35,000 people. It is part of the New Hampshire Rivers Management Protection Program. It was one of two rivers studied by the New Hampshire Department of Environmental Services to reach data and recommendations about allowable "instream flow".
