The open space included in the Marchesiani Farmlands and McKenna Marsh area comprises a number of properties in Hingham and a large parcel in Norwell. The parcels generally are formed around Accord Brook and its abutting wetlands as the brook flows across Main Street to the crossing of Prospect Street into Wompatuck State Park. Through this run the brook is generally bound by uplands of Liberty Plain following Prospect Street to Mast Hill on the north and Queen Ann’s Corner, Grove Street and Prospect Street veering towards Prospect Hill on the south and east. Two characteristics of the land which have shaped its use over time are that it is largely wetlands making it a water supply resource and it is relatively flat lending itself to farming.
Accord Brook threads through the area, making it important to water supplies of Hingham and Norwell, which has town wells and 205 acres of publicly owned land abutting the southern border. More than 100 acres here include a freshwater marsh once used as a waterfowl preserve, with a beaver dam of unusual length and linearity. Considerable high ground and open woods provide easy walking and vantage points to observe waterfowl. Large white cedars can be seen from the trail that skirts eskers toward the northern margin. In 2007, the Conservation Preservation Act purchase of the Gladys Cushing property off Scotland Street conserved an additional 2+ acres behind an affordable housing site. Also within the McKenna Marsh land is a 9.75-acre parcel, acquired in 2012, known as the Scotland Street Meadow, now reverting to forest. Good for observing nature, with an informal trail system. Park on Scotland Street (not at Housing Authority property). Due east of the McKenna Marsh acreage is a 1.4-acre property, in the Wanders Drive neighborhood, donated by Irene Ann Bucken in 1994. A mix of wetland and upland; no formal trails or parking.
Abutting Main Street are 25 acres of historic farmland that were once a part of Pushcart Farm, originally purchased by the Marchesiani family in 1934. As with many currently wooded properties, these lands were mostly held open for pasture and agriculture. More than 10,000 tomato plants were grown here, along with cucumbers, strawberries and other vegetables. Through the good will of the Marchesiani family and the developer of Black Rock Golf Course, this property was obtained in 2001 in exchange for an inaccessible conservation tract on Old Ward Street. This land connects Main Street to more than 100 acres of conservation land in Hingham and to the Norwell water well fields. It borders Accord Brook and McKenna Marsh and includes a spectacular pine grove. The mown field (entrance marked by granite posts) on Main Street recalls the agricultural history of the town. Cart paths through the property make for easy walking.
There are two major points of access to the Hingham property. The property can be accessed at the entrance to Marchesiani Farmlands, between 1126 and 1142 Main Street, or from Scotland Street just south of Richard Road. Parking is available near the Main Street Entrance at the Middle School, but is limited to non-school hours. At the Scotland Street entrance there are three dirt parking spaces available from dawn to dusk. The route for the walk follows a single path linking the two entry points and extending east of the Scotland Street Entrance. The described routes go from the Scotland Street entrance to the east then returning on the same trail, continuing west past Scotland to Main Street. At Main Street the route reverses direction and ends the walk at Scotland Street. Since the route is a round trip on the same path, the visitor can choose to begin the walk at either entrance and cut the walk short if he/she so chooses.
