Suffolk Downs is a former thoroughbred racetrack located in East Boston, Massachusetts. Opened in 1935, it was known for hosting horse racing events and was one of the oldest tracks in the United States. The facility featured a one-mile dirt track and a turf course, attracting both local and national racing enthusiasts. In 2019, Suffolk Downs ceased live horse racing operations, primarily due to financial challenges and competition from other forms of entertainment. The site has since been considered for redevelopment, with plans that may include residential and commercial projects, reflecting the changing landscape of the area.
