Stockholm (AFP) – Queen Silvia of Sweden says the royal palace where she resides is haunted, according to a documentary to be aired on public television on Thursday. “There are small friends… ghosts. They’re all very friendly but you sometimes feel that you’re not completely alone,” Queen Silvia says in the documentary by SVT. “It’s really exciting. But you don’t get scared,” she adds. Drottningholm Palace, which is on the UNESCO world heritage list, was built in the 1600s on Lovon island in Stockholm.
