Restoration of Historic Tainan Sugar Factory Red Building Lab Begins

The laboratory of the former Yanshui Port Sugar Manufacturing Co., Ltd. Annan Sugar Factory in Tainan City, a historic building that bore witness to the golden age of Taiwan’s sugar-making industry, officially broke ground for its restoration project today, thanks to the anticipation of various local sectors and the injection of resources from both central and local governments. Nestled in Tainan City’s Yanshui District and affectionately nicknamed the "Red Building" by local residents and cultural historians, this two-story brick structure is not only an important testament to the development of Taiwan’s modern industry during the Japanese colonial period, but was also a pivotal core site in the history of Taiwan's sugar industry where the island’s first batch of cultivated-land white sugar was test-produced. With the launch of the restoration project, this cultural asset, which has been sealed for years and carries rich local memories, will be given a new lease of life in the future, becoming a vital cultural hub connecting the past and the future.

The history of the Annan Sugar Factory, where the laboratory is located, dates back to the Japanese colonial period. At that time, to achieve the goals of the Southern Expansion Doctrine and self-sufficiency in sugar within the island, the Japanese government actively fostered Taiwan’s sugar industry, transforming traditional manual sugar-making into scaled capitalist industry through capital concentration and the introduction of modern machinery. The Yanshui Port Sugar Manufacturing Co., Ltd. was one of the industry leaders, and the Annan Sugar Factory served as one of its core production bases. The laboratory building, known as the Red Building, adopted a rare two-story brick structure for its time, with an exterior and construction methods bearing strong industrial architectural characteristics of the Japanese colonial period. It was not only a space for technological research and development, but also the central hub for scientific management and quality control within the sugar factory.

This laboratory holds a significant position in the history of Taiwan's sugar industry, with its most celebrated achievement being that it witnessed the successful trial production of Taiwan's first batch of cultivated-land white sugar. Prior to the Japanese colonial period, traditional sugar-making in Tainan mostly produced brown sugar or raw sugar, which had lower purity and levels of refinement. With innovations in sugar-making technology and the continuous research and experimentation of scientists in the laboratory, the Annan Sugar Factory successfully broke through technological bottlenecks and test-produced high-quality cultivated-land white sugar. This not only significantly enhanced the competitiveness of Taiwan's sugar industry in the international market, but also marked a brand-new modernization phase for Taiwan's agriculture and food processing technology. As the birthplace of this historical achievement, the bricks and tiles of the Red Building encapsulate the dedication and wisdom of countless engineers and technicians of that era.

With the restructuring of Taiwan's sugar industry and changes of the times, many sugar factories faced transformation or demolition due to declining output value or urban development. The laboratory in Annan also once fell into silence amidst overgrown weeds, even facing crises such as structural damage and roof leaks due to years of disrepair. However, in recent years, public awareness in Taiwan regarding the preservation of local history and cultural assets has been rising. The Tainan City Government and relevant cultural departments recognized the importance of the building, known as the Red Building, to the local historical fabric, and actively promoted cultural asset review and restoration plans. Through multifaceted efforts, securing funding, and rigorous architectural research and design, restoration finally officially commenced today. This is not only a physical rescue of a historic building, but also a profound solace for the collective memory of the locality.

In the professional field of cultural asset restoration, the restoration of century-old brick industrial buildings of this kind often faces immense challenges. It is necessary not only to maintain their original historical appearance and structural safety, but also to balance the possibilities for future adaptive reuse. The restoration team must adhere to cultural asset preservation regulations, using traditional construction methods and homogeneous materials for repairs to preserve the building’s original appearance and traces of time as much as possible. The local cultural and historical community holds high expectations for the restoration of the Red Building, believing that upon its completion in the future, it will not only generate a synergistic effect with surrounding cultural facilities such as the Annan Filming Base, but also connect rich historical and cultural attractions in the Yanshui area, such as the Yanshui Beehive Fireworks Festival and Qiaonan Old Street, injecting brand-new cultural tourism momentum into the locality and allowing more people to understand Taiwan's early sugar industry splendor and industrial development trajectory through this Red Building.
