Hillwood Estate
This isn't your typical museum. Hillwood Estate is a unique fusion of art, natural beauty, and history, and it's sure to make your jaw drop upon entry. Big cities like Washington aren't usually known for lush, green spaces, but they definitely do exist. The estate features a pond, bright green flora, rocks, water features, bridges, and an art collection. Hillwood Estate was purchased by socialite Marjodie Merriweather Post in 1955, and after many years spent creating a collection of antiques and art, she decided to turn the estate into a museum. She welcomed the public into her home, and now, people can learn all about her and her breathtaking garden. The indoor and outdoor space spans over 13 acres and does require a ticket for entry.
