Kellie’s Castle (aka Kellie’s Folly) is a castle located in Batu Gajah, Kinta District, Perak, Malaysia. The unfinished, ruined mansion, was built by a Scottish planter named William Kellie Smith. According to differing accounts, it was either a gift for his wife or a home for his son. The castle is situated beside the Raya River (Sungai Raya), which is a tributary to the Kinta River.
The construction of this house was started in 1915 by William Kellie Smith but it came to a full halt upon his sudden death in 1926. The solitary castle, looks almost surreal in these wild plantations of Perak, projecting a strong personality and an aura of mystery.
Besides being haunted, the castle is believed to have hidden rooms and secret underground tunnels, one of which leads to the Hindu temple through the Kinta River. However, this tunnel has now been sealed for safety reason.
