A Longboat Key estate that hit the market this week is Sarasota County’s most expensive listing ever, the listing agent says.

Located behind the gates of the Longboat Key Club, the property — known as Serenissima, which means “the most serene” in Italian — features 19,300 square feet of living space overlooking the Gulf of Mexico. The house has six bedrooms, six full bathrooms and two half-baths as well as a 12-car garage.

Among the highlights are a marble hall with a glass dome, grand salon that can accommodate 100 guests, Venetian murals, a 10-seat home theater, chef's kitchen and sun room overlooking the infinity-edge pool. The property also contains 145 feet of beach frontage.
