Back in 2003, Business magnates and brothers David and Frederick Barclay bought Brecqhou, an island just off the coast of the British Channel Islands. They built a medieval castle, and until recently, the island was entirely off-limits to civilians.
The landscaping took years of work to complete, and now select guests can visit the olive grove, fruit and vegetable garden, vineyard, and ponds.

Hollywood legend Gene Hackman used to own a tiny island among Washington's San Juan Islands. On it, he built the main house that includes 3-bedrooms with a 360-degree deck and two guest houses for his visitors.
