This island is private property.
There is a spectacular little island in the Iseo Lake, in the province of Brescia. The structures on it are built in a neo-Gothic style— meaning the main property is pretty much a fairy tale castle. The island has its own small harbour, two magnificent towers and a park of conifers that introduce the sweet scent of pine into the air.
In the XIX century, the island became a property of Duchess Felicita Bevilacqua La Masa, the nit was purchased by Vincenzo Richeri, a Royal Navy Captain. In 1910, Richeri built a neo-Gothic castle on the island, and around it he created a garden full of conifers, a marina, and two light towers. The latter illuminate a cove with a path leading straight up to the villa.
This abode features a rectangular layout, with two floors. Thanks to its turret, battlements, and light stone walls, the villa appears quite spectacular and evocative. It actually stands on a rock overlooking the lake.
I wish I had enough money to buy an island and build a castle on it lol
That’s the thing, for this particular island, per the link:
