Erasmus Castle (Erasmuskasteel in Afrikaans), also known as "Die Spookhuis" or "The Haunted House", is an imposing mansion situated on a hill in the Erasmuskloof suburb of Pretoria, South Africa.

Originally owned by George Dean Erasmus, it is a unique landmark in the city and rumours of ghosts and supernatural encounters in and around the residence are plentiful.

In the late 1960s, the Erasmus heirs were compelled to sell the farm "Garsfontein" to the Pretoria Municipality[1] as new highways were being developed east of the city.

In 1975 the board instructed Billy Nel, assisted by Dr Elise Labuschagne, Hannes Meiring and Anton Janson[1] to restore the mansion to its original form.

[2] The mansion continues to sprout new and exciting tales and remains popular with ghost hunters and historical societies to this day.
