Boston Edison retained the land until 1995, when the land and easements were purchased by O'Donnell Sand & Gravel. It became an industrial center used by Monsanto starting in 1929, with Monsanto selling the parcel to Boston Edison in 1983. The land was acquired by Merrimac Chemical Company in 1917. That year Cochrane Chemical Company purchased a portion of the plot adjacent to New England Chemical's former factory, with the Cochrane factory experiencing heavy use during World War I. New England Chemical started a plant on the site in 1868, before going out of business in 1872. Using a corner of White Island, in 1854 the Mystic River Bridge was built across the river. Prior to any backfill, as early as 1804 a dye house had been built on the land, which was later occupied by Cochrane Chemical Company. A section of the plot had been known as White Island in the 1800s, with the island later becoming part of the mainland as backfill expanded the shoreline along the Mystic River. With the project later renamed Wynn Boston Harbor, around 30 of those acres had previously been set aside for industrial use and were inaccessible to the public for more than 100 years. In January 2015, Wynn Resorts purchased 33 acres (13 ha) of land along the Mystic River in Everett, Massachusetts, and announced plans to build the resort- casino Wynn Everett on the plot. The undeveloped parcel in the upper-center of the image, between the railroad bridge (left) and the windmill (right), was used for industrial purposes in the 1800s, before being purchased for the casino in January 2015.

Public amenities of the year-round harborwalk include a picnic park, paths for bikers and pedestrians, viewing decks, waterfront dining and retail, a performance lawn, floral displays, boat docks, and public art. After a remediation process to clean the site, Wynn Resorts constructed an integrated resort with a hotel, a harborwalk, restaurants, a casino, spa, retail outlets, and meeting and convention space. It opened on June 23, 2019, at a total cost of $2.6 billion. Its development rehabilitated a 33-acre parcel of land previously used for industrial purposes. The resort is in a commercial-industrial area on the Mystic River, about 5 miles (8.0 km) from downtown Boston. It is owned by Realty Income and operated by Wynn Resorts. 42☂3′40.06″N 71☄′12.73″W / 42.3944611°N 71.0702028°W / 42.3944611 -71.0702028Įncore Boston Harbor site on the Mystic River in February 2019Įncore Boston Harbor (previously referred to as Wynn Everett and Wynn Boston Harbor) is a luxury resort and casino located in Everett, Massachusetts (on the border with Boston).
