Located in the hills, this site serves as a reminder of Lebong's glorious past as one of the largest gold-producing regions in the archipelago. ## Key facts - **address**: Lebong Tambang Village, North Lebong District, Lebong Regency - **entrance fee**: Rp 5,000 - **opening hours**: Every day, 08:00 - 17:00 # Golden Traces in Rejang Land: The History and Heritage of Lobang Kacamata Lobang Kacamata is not just a hole in a hillside; it is a silent monument to the era of the gold rush that once swept through Bengkulu in the early 20th century. Located in Lebong Tambang Village, Pinang Belapis District, Lebong Regency, this site is an integral part of the Dutch East Indies colonial mining history that transformed the economic and social landscape of southern Sumatra. ## Origins and Development Period The construction of Lobang Kacamata began in the early 1900s, specifically around 1906, when the Dutch East Indies colonial government, through the mining company *Mijnbouw Maatschappij Redjang Lebong*, started exploiting the mineral wealth beneath Lebong's earth. The name "Lobang Kacamata" itself does not originate from a technical mining term, but rather is a local designation that emerged due to its visual appearance. Viewed from a distance or from the foot of the hill, there are two tunnel entrances situated side-by-side and circular in shape, resembling a pair of eyeglass lenses. This unique visual feature makes it the most easily recognizable icon among hundreds of other mine shafts scattered across the Lebong region. The tunnel was built to penetrate hard rock layers to reach the extremely rich gold and silver veins in the area. ## Architecture and Construction Details Architecturally, Lobang Kacamata represents the underground civil engineering expertise of its time. Unlike traditional mines that were often narrow and irregular, Lobang Kacamata has a more planned structure. The tunnel was dug horizontally through rocky hills with a sufficiently large diameter, allowing mining equipment and workers to enter and exit with high intensity. The tunnel walls show traces of manual carving and precise use of explosives. The interior construction includes wooden support systems, most of which have now petrified or crumbled with age, as well as a simple drainage system to channel groundwater and prevent flooding of the work area. Another unique feature is the natural ventilation system that utilizes the air pressure difference between the two main openings, an aerodynamic principle that ensured workers in the past received a supply of oxygen even when deep underground. ## Historical Significance and Key Events Lobang Kacamata is a symbol of Lebong's golden age as the "Gold City." At its peak between 1910 and 1930, the mine output from Lebong, including that from Lobang Kacamata, contributed significantly to the treasury of the Kingdom of the Netherlands. There are even historical records mentioning that the gold adorning the top of the National Monument (Monas) in Jakarta originated from Lebong's earth, processed through mining facilities in the surrounding area. This site also bears silent witness to the forced labor system (*heerendiensten*) and the mobilization of contract laborers from various regions, especially from Java. Thousands of workers were brought to Lebong to work under harsh and dangerous conditions. Mining accidents and disease outbreaks in the workers' settlements are a dark part of the history behind the magnificent gold output sent to Europe. ## Associated Figures and Periods The exploitation of Lobang Kacamata is closely linked to Dutch geological figures like Edward de Groot and the executives of *Mijnbouw Maatschappij Redjang Lebong*. Furthermore, the site is also associated with the Japanese occupation period (1942-1945). When the Japanese arrived, they took over these mining facilities to fund their war efforts in the Pacific. After Indonesia's independence, the management of the mine briefly transferred to the Indonesian government before large-scale mining activities were eventually halted due to dwindling reserves and internal conflicts. ## Preservation Status and Restoration Efforts Currently, Lobang Kacamata has been designated as a Cultural Heritage Site by the Lebong Regency Government. Its status has shifted from an active industrial area to a historical and educational tourism destination. Restoration efforts tend to be conservative, focusing on maintaining the original form of the openings without adding many modern structures that could damage its historical value. The local government has built road access and concrete stairs to facilitate tourist access to the mouth of the openings, which are located at an elevation. Nevertheless, preservation challenges remain, particularly concerning illegal gold mining activities in the vicinity, which sometimes threaten the stability of the soil structure around this historical site. ## Cultural and Social Meaning For the Rejang people who inhabit the Lebong region, Lobang Kacamata is not just a Dutch relic, but a symbol of pride and the natural wealth of their homeland. This site often serves as a backdrop for folk tales about past prosperity. Culturally, the existence of this opening also serves as a reminder of the social transformation in Lebong, from an agrarian society to a heterogeneous mining society. ## Unique Historical Facts One rarely known unique fact is that inside the labyrinth of Lobang Kacamata's tunnels, the air temperature remains stable regardless of whether the weather outside is very hot or cold. This is due to the depth and the ancient rock material that makes up the hill. Additionally, some geological researchers mention that the rocks around Lobang Kacamata contain traces of ancient volcanic activity, which is the reason why this region is so rich in precious metal minerals. In conclusion, Lobang Kacamata is a physical narrative of human ambition, past engineering prowess, and Indonesia's extraordinary natural wealth. Preserving this site means preserving the nation's collective memory of how gold from Lebong once dazzled the world and became part of the global history of precious metal trade.
