The price of Round Hill Manor has been cut by $11 million, a year after a similar reduction that combined have cut the tag on the Greenwich estate to just below $29 million.

Totaling more than 17,000 square feet of space on 40 acres of grounds at 521 Round Hill Road, the mansion was built in 1921 and dubbed Dunnellen Hall previously.

After the 2007 death of former owner Leona Helmsley, the estate was originally listed for $125 million, ultimately being purchased in 2010 for $35 million. It was put back on the market in 2016 for $49.9 million, with the price reduced by $10 million last year and now by another $11 million.
