Is a privately-owned property smack in the middle of the beachfront area of Francis Ford Coppola's boutique resort in Placencia, the Blancaneaux Turtle Inn. From the sign outside you can see that the owner is intent on selling...though possibly not to the formerly talented movie director turned winemaker-hotelier!
Sadly, one of Placencia's north shore architectural novelties appears to have been demolished. Unlike the clapboard shacks and thatched cabañas that typically front the sea, this looked more like something the Germans would have left on the beach near Calais. Its owner was an eccentric American millionaire I met back in '89; an avid reader of Robert Heinlein - appropriate, because his home also bore a striking resemblance to a concrete flying saucer.
