William K. Vanderbilt II enjoyed traveling around the world, but never so much that he got distracted from his true passion: the sea. He collected marine specimens on his journeys—along with other artifacts—to one day display at his Long Island estate. His collection's first 1922 iteration was aptly called Hall of Fishes. But in the almost-century since then, it's expanded into a museum complex that's home not only to marine life, but to other artifacts of modern history.
- Size: 43 acres of waterfront land; 30,000+ artifacts.
- Permanent Mainstay: the historic, Spanish Revival-style mansion, whose 24 rooms feature intricate ironwork and antique furnishings. On tours, visitors also take in what elite family life was like in the first half of the 20th century.
- Eye Catcher: The rolling lawns. The mansion is surrounded by acres of manicured flowers and greenery that looks especially lush in summer.
- Hidden gem: Animal species Vanderbilt discovered himself. Keep an eye out for them in the museum.
- Don't Miss: the Planetarium, a modern addition. On its 60-foot dome, visitors can watch recreations of landmark celestial events, such as Orion trying on belts at the space-mall.
