"Round Hill"

 residence, country house, interesting place

'Round Hill' was for over twenty years the home of Colonel Edward "Ned" Green; son of the notorious Hetty Green, who was nicknamed "The Witch of Wall Street" as a result of her shrewd business investments. When Hetty died in 1916, she left an estate estimated to be between $100-$200 million, making her the wealthiest woman in the world at the time. Ned and his sister each inherited approximately $75 million. Following his mother's death, he decided to construct a large and comfortable mansion; capable of showing his immense wealth. He hired architect Alfred C. Bossom to carryout his dream; which finally came to life in 1921, at a cost of $1.5 million, measly compared to the Green fortune.

In 1948, his sister and heir donated the entire property to MIT, which used the 240-acre (0.97 km2) estate for educational and military purposes. The mansion is now comprised of multiple private luxury condominiums and the estate has been turned into a gated community and golf course.
