17. Hillwood House Museum and Gardens – Washington
Marjorie Merriwether Post, the founder of General Foods, was once the richest woman in the world. Marjorie built a 40-room “Georgian Mansion” surrounded by a huge garden. It has stone lanterns, a pagoda, a rock pool, and a Japanese garden blended with an American-style touch. More than 10 gardens along the 13 decares of land are worth seeing. Visitors prefer this place for an afternoon tea and a quiet environment, away from the noise and chaos of the big city after its death.
