Near the coastal Swedish town of Molle is Ladonia, a series of large wooden towers built by artist Lars Vilks. Unlike driftwood shacks, Ladonia's towers are made from wood found in the nearby forest. Several of the towers are quite tall and are open for the public to climb. After pressure from local authorities to remove the project, Lars made Ladonia it's own country with it's own currency.
