In a country torn by bloody civil war, a young man seizes power. In his native tongue, he is called Dracula. This is not the vampire, Count Dracula, but a real historical figure: a Romanian prince. Dracula was a warlord who became known all across Europe for both his breathtaking courage and his terrifying cruelty. But he also left an enduring legacy. Not just in blood, but also in brick, mortar, and stone. He constructed palaces. He founded the city that was to become his country's capital. He also built one of Eastern Europe's most breathtaking mountaintop castles. Now, with state-of-the-art computer animation, we'll bring Dracula's lost world back to life: his birthplace in the fortified town of Sighisoara; the gothic splendor of Transylvania's Bran Castle; the sumptuous palace of Targoviste; and the real castle Dracula, Poenari.
