A man runs in the Central Park in New York, the United States, on April 16, 2019. With a history of over 160 years, the Central Park was created as the nation's first major landscaped public park. It is one of the most frequently visited park in the United States, with over 40 million visitors per year nowadays. Set in the middle of bustling Manhattan and covering an area of 341 hectares, its grounds serve as a safe haven, not only for athletes, musicians and strollers, but also for hundreds of migratory birds each year.
