The Wang Institute of Graduate Studies was an independent educational institution founded in 1979 by computer entrepreneur An Wang. Its purpose was to provide professional and continuing studies in the nascent field of software engineering. It was accredited by the New England Association of Schools and Colleges in 1983. Faculty members were recruited from industry and students were required to have a minimum of three years prior experience in industry as a condition of acceptance. The Institute acquired its 200-acre (0.81 km2) campus from the Marist Brothers who had operated a seminary on the site since 1924. Located in Tyngsborough, Massachusetts, it housed two divisions: The School of Information Technology and a fellowship program in East Asian studies. The Institute never grew beyond a dozen or so faculty. As a result of declining business fortunes Dr. Wang closed the Institute, graduating the last class on August 27, 1988. The campus was transferred to Boston University where it served as a corporate education center. Today, it is the location of the Innovation Academy Charter School.

Pheasant Lane Mall, occupying 979,427 square feet (90,992 m2), is one of the largest shopping malls in the state of New Hampshire and the focal point of the commercial area in south Nashua. As of 2023, the mall has about 139 stores and kiosks, including four anchor stores: Dick's Sporting Goods, JCPenney, Macy's, and Target with one vacant anchor last occupied by Sears, plus 15 restaurants. Since 2012 it has been owned and managed by Simon Property Group of Indianapolis. Located just south of Exit 1 of the F.E. Everett Turnpike/U.S. Route 3 in Nashua and directly at northbound exit-only Exit 91 (Old Exit 36) off US 3 in Tyngsborough, Massachusetts, the property straddles the state line, although the entire mall is in New Hampshire. Proximity to the border has long drawn shoppers from Massachusetts seeking to take advantage of New Hampshire's lack of a sales tax. Approximately one third of the parking lot and water runoff area is located in Tyngsborough. Shoppers who park in front of the former Sears entrance closer to Buffalo Wild Wings walk across the state line in front of the building on the sidewalk to get to and from their cars. The JCPenney store was originally built with a square corner that reached slightly across the border into Massachusetts, but was then modified to an unusual pentagonal shape at the state line to keep it entirely within New Hampshire by a few inches. Without that modification, the entire mall would have been subject to Massachusetts sales taxes, even though only a few inches of the structure was in Massachusetts.
