Ever dreamed of owning your own secret citadel in a beautiful region of Italy, wandering along its fortified walls like a monarch surveying their kingdom? For less than the price of a townhouse in central London or an attic apartment in Rome's historic center -- that dream can now come true.

The medieval castle and hamlet of Serravalle, half-way between the cities of Modena and Bologna in Italy's northern Emilia Romagna region, is up for sale for 1.9 million euros, or about $2 million. Already livable and fitted with heating, it requires just minimal fixes -- and the price is negotiable.
