Hollywood Roosevelt Hotel, Los Angeles, United States

Marilyn Monroe, Errol Flynn, Montgomery Clift... celebrity-loving ghost hunters are spoilt for choice at LA's Hollywood Roosevelt Hotel.

An institution during Hollywood's golden age, the property's history is star-studded - it was even the location for the very first Oscars - and many of the silver screen legends who frequented the hotel while alive are believed to have returned since their deaths.

Marilyn Monroe, who spent two years living here and was especially fond of one of its poolside suites, is still seen in the reflection of a full-length mirror in the room, while former Hollywood heart-throb Montgomery Clift has been heard playing his trumpet in the room he stayed in for three months while filming "From Here to Eternity," 1928.

Dragsholm Slot, Odsherred, Denmark

Located in the heart of the beautiful Odsherred peninsula in Denmark, this 800-year-old castle-turned-luxury hotel is regularly hailed as one of the most haunted castles in Europe.

It;s thought there could be as many as 100 ghosts haunting the corridors of Dragsholm Slot.

The three best-known ghosts are the grey lady, the Earl of Bothwell — a Scottish royal and formal prisoner who is said to ride around the courtyard on a phantom horse, and the white lady.

Said to be a young noble who was imprisoned in the castle by her evil father, rumours of the white lady gained momentum after builders in the 1930s discovered a skeleton in a white dress entombed within one of the walls.
