Situated on a rise at Tanjung Kubong is the famous 'Chimney', a 106 feet high red brick stack believed to be linked to the coal mining days of Labuan. The Chimney, 106 feet tall, was made from more than 23,000 pieces of red bricks imported from England. The bricks layering and works are typical of British style.
The 'Chimney' was long thought to be nothing more than a ventilation shaft. However, recent findings revealed that there were no traces of smokes or burning to suggest its use as a chimney as popularly believed. Careful digging has revealed at least 12 layers of bricks beneath the surface. The structure sits firmly on a large tract of limestone rock containing rich kaolin or porcelain clay, which provided the strong foundation.
The 'Chimney' is still very much a mystery until today. Various hypotheses have been put forward to its purpose. Some said it was an unfinished mansion. While others said it was a light house beaconing passing ships. In its heyday, a thriving settlement was built at the sea front area below the Chimney. It was then used as a bell tower to announce the arrival of ships to the residents below. It has become an intriguing riddle that fascinates locals and visitors alike.
