Salem Willows Park

Salem Willows is an oceanfront park in Salem, Massachusetts. It is named for the European white willow trees planted there in 1801 to form a shaded walk for patients convalescing at a nearby smallpox hospital. The area became a public park in 1858, and became a summer destination for residents of Boston's North Shore, many of whom escaped the heat of the city on newly popular streetcars. Construction on the amusement park began in the summer of 1877 by the Naumkeag Street Railway Company which had extended its horsecar system to the park.
