Wonderland Greyhound Park is a closed greyhound racing track located in Revere, Massachusetts formerly owned by the Westwood Group. It was constructed on the site of the former Wonderland Amusement Park. Wonderland opened on June 12, 1935 and formerly offered 361 races during its 100-day, April to September racing period.As a result of a statewide ban on dog racing which took effect on January 1, 2010, the track offered only simulcast wagering, but completely closed its doors on August 19, 2010. The track laid off the remaining 75-80 workers and closed its doors after Massachusetts governor Deval Patrick vetoed a gaming bill that could have allowed the park to add slot machines.With the end of its greyhound racing, Wonderland formed a partnership with nearby Suffolk Downs horse track to build a casino on the site, but this plan also allows the option of the track being redeveloped for commercial or mixed uses.HistoryWith the legalization of Parimutuel betting by the Massachusetts Legislature in 1934, the idea of Wonderland Greyhound Park was made a possibility. The track was constructed on the site of the former Wonderland Amusement Park in Revere, which had been converted from an amusement park to a bicycle track after the park closed in 1911.
