Villa del Balbianello on Lake Como Italy. I was lucky enough to see the inside of this Villa a few years ago. It was breathtaking. The original owner was an eccentric Millionaire, who lived there alone. His greatest fear was being kidnapped, and to that end, he had a secret tunnel under the villa, leading to a waterway that housed an &quot;escape&quot; boat.  The arched building on the top right is actually part of a beautiful gazebo, in the garden. I believe a few movies have been shot here.
