$25 million Italian Palazzo on Harrington Sound is on the market.

Owned by Canadian multi-millionaire Rockwell Schirallli and his wife Sammy, visitors could be forgiven for thinking they were staying at one of the famous Lake Como homes once they crossed a bridge leading to the Smith's home.

'Deepwater' is a sprawling four bedroom, four bath waterfront estate with a four bedroom, four bath guest cottage overlooking Harrington Sound.
