**Abstract:** Social media is a rapidly developing field in architecture and landscape research, which is used to understand public opinions and landscape use. The year 2022 sees the 200th birthday of Olmsted, the founding father of landscape architecture in America. While we commemorate Olmsted's ground-breaking contribution to the landscape architecture discipline, in-depth analyses are always required to examine historic legacies for their current relevancy. Taking his first practical work, New York Central Park, as an example, this paper systematically revisits Olmsted's park design theory and vision, and investigates its post-occupancy conditions from 11,501 posts on TripAdvisor. The results show that the current park use pattern confirms the validity of his scenic image theory. At the same time, his design works have become increasingly popular as public projects to foster social interaction.
