Media titan Oprah Winfrey purchased her home in Montecito, Calif., in 2001. She has dubbed the mansion “The Promised Land,” and, though accounts vary, the consensus is that she paid between $50 million and $55 million, then spent additional millions renovating it. The estate has both mountain and ocean views, 10 fireplaces and the landscaping features a rose hybrid specially bred over five years by her landscaper.

The property also includes a teahouse. The structure originally was meant to serve as a cutting room for her landscaper, but according to Oprah.com, she fell in love with the building and claimed it for herself, then turned it into a tranquil refuge where she goes to get some much-needed peace and quiet. "It's my dream, having a place like this," she said. "Some people ask, 'Why do you need more space?' And I tell them, 'I need it to restore myself.'"
