The Castle Take a trip, if you dare, to the heart of Transylvania and the 16th-century Banffy Castle. This totem of Gothic architecture is nicknamed the Versailles of Transylvania and though it may cast ominous shadows across the Romanian landscape, it's also the backdrop and inspiration for Electric Castle. Situated just outside Cluj-Napoca, Romania's second city, Electric Castle has grown from 32, 000 people in 2013 to a triumphant 121, 000 revelers most recently. Fortunately, the only thing that any of them has come to drink is beer, so you can leave your wooden stakes and garlic at home. More Info below.
