In Karanganyar, Central Java, stands a historic building that now holds many mysterious tales: the Colomadu Sugar Factory. Once a major center for sugarcane production, today it is better known as one of Indonesia’s most haunted locations.
The History of Colomadu Sugar Factory
The Colomadu Sugar Factory was built in 1861 under the initiative of Mangkunegara IV, a ruler of the Surakarta region. The name “Colomadu” means “Mountain of Honey,” symbolizing the hope that the factory would bring sweet prosperity.
During its golden era, the factory became a vital economic hub, providing jobs for many local residents. However, after facing numerous challenges, including damage from wars and the decline of the sugar industry, the factory ceased operations in 1998.
Since its closure, the abandoned factory has become a breeding ground for eerie stories.
Ghost Stories Behind the Old Walls
The factory’s large, empty buildings create a chilling atmosphere. Many who have entered the site claim to have experienced strange phenomena. Some report seeing shadowy figures, hearing the sounds of machines running at night, or smelling burnt sugar even though production has long since stopped.
One of the most common tales tells of ghostly factory workers who continue their labor into the afterlife. According to legend, the souls of those who lost their lives in work accidents still “haunt” the area.
A Factory Wrapped in Mystery
Not only do locals share these stories, but ghost hunters and urban explorers also list the Colomadu Sugar Factory as a favorite destination. The deserted atmosphere, decaying structures, and lingering past create an unforgettable experience.
Some photographers claim that their pictures captured unexplained phenomena—such as human silhouettes or sudden, dense mists.
Revitalization and Controversy
In recent years, the government and private sectors have made efforts to transform the Colomadu Sugar Factory into a cultural and event venue. Parts of the structure have been renovated while maintaining the original architecture to preserve its historical value.
However, the revitalization sparked some controversy. Many feared the renovations might disturb the “old inhabitants,” and several workers reported strange occurrences during the restoration process.
The Colomadu Sugar Factory stands as a witness to Indonesia’s sugar industry history and remains a storehouse of lingering ghost stories. For some, it serves as a reminder of the powerful memories of the past. For others, Colomadu is a gateway to the unseen world.
Visiting the Colomadu Sugar Factory means stepping between reality and a world filled with mystery—where history and ghost tales walk side by side.
