Encore 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). It is owned by Realty Income and operated by Wynn Resorts. The resort is in a commercial-industrial area on the Mystic River, about 5 miles (8.0 km) from downtown Boston. Its development rehabilitated a 33-acre parcel of land previously used for industrial purposes. It opened on June 23, 2019, at a total cost of $2.6 billion. 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. Public amenities of the year-round harborwalk include a picnic park, paths for bikers and pedes
