Dutch Barracks Mempura

Colonial Traces on the Banks of the Mempura River: The Complete History of the Siak Dutch Barracks

Tangsi Belanda Mempura stands as a silent witness to the political and military dynamics in the eastern coastal region of Sumatra, particularly in the heart of the Sultanate of Siak Sri Indrapura. Located in Mempura Village, Siak Regency, Riau Province, this old building complex is not merely brick ruins, but a physical artifact that records the transition of power from sultanate sovereignty to the colonial hegemony of the Dutch East Indies.

Origins and Construction Period

The construction of Tangsi Belanda Mempura is inseparable from the political agreements between the Sultanate of Siak and the Dutch colonial government (VOC to the Dutch East Indies government). Historically, the complex began construction in the mid-19th century, precisely around the 1860s. Its construction was triggered by the increasing Dutch military presence in the Riau region to secure trade routes in the Strait of Malacca and to monitor the internal movements of the sultanate.

The location of Mempura was chosen due to its strategic position opposite the administrative center of the Sultanate of Siak (Asserayah Al Hasyimiyah Palace). By placing the military in Mempura, the Dutch could exert direct psychological and physical surveillance over the Sultan without having to be within the palace complex. The existence of these barracks marked an era where Dutch influence began to strongly grip the bureaucracy and security in the mainland Riau region.

Architecture and Construction Details

Architecturally, Tangsi Belanda Mempura applies the Indische Empire Style, which was very popular in the 19th century. This style blends European neoclassical aesthetics with adaptations to the tropical climate of the Nusantara. The complex consists of several main buildings that served as soldier barracks, administrative offices, armories, and detention houses (prisons).

The building walls were constructed with a thickness of 30 to 50 centimeters, using red brick material without iron reinforcement, but bonded with a mixture of lime, sand, and egg whites as a very strong natural adhesive. The main characteristic of these buildings is the presence of large windows with high ventilation (louvers) for maximum air circulation. Large Doric-style pillars support the front of the buildings, giving an impression of sturdiness and authority. One of the unique aspects of its construction is the ancient, well-organized underground drainage system, ensuring this military complex remained flood-free despite being close to the Siak River.

Historical Significance and Related Events

Tangsi Belanda Mempura functioned as the Dutch military command center for the eastern coastal region of Sumatra. Its primary function was as a defense fortress and training ground for KNIL (Koninklijke Nederlandsch-Indische Leger) soldiers. However, behind its military function, this place holds a dark history as a detention center for local fighters and individuals deemed defiant of colonial policies.

One of the important events related to this site was the tension between Sultan Syarif Kasim II and the colonial government. These barracks became a symbol of Dutch pressure on Siak's sovereignty. During the Japanese occupation (1942–1945), the function of these barracks shifted to become a Japanese army headquarters (Rikugun). Many local oral accounts mention that the underground rooms in this complex were once used as torture sites during that period of power transition.

Important Figures and Periods

The prominent name always associated with the existence of these barracks is Sultan Syarif Kasim II. Although these barracks belonged to the Dutch, their presence influenced the Sultan's diplomatic policies. He had to balance maintaining the sovereignty of the Siak people with the presence of foreign military forces just a stone's throw from his palace.

Furthermore, these barracks also bore silent witness to the activities of Dutch Residents and Assistant Residents stationed in the Siak region. It was here that decisions regarding taxes, rubber trade monopolies, and navigation regulations on the Siak River were formulated. The golden period of the use of these barracks ended with the Dutch defeat by Japan, which was followed by the proclamation of Indonesian independence, during which this asset was eventually nationalized.

Preservation and Restoration Status

After being neglected for decades and overgrown with bushes, the Siak Regency Government began serious steps to restore Tangsi Belanda Mempura in 2017. The restoration was carried out in stages by the Ministry of Public Works and Public Housing (PUPR) in collaboration with the Center for Cultural Heritage Preservation (BPCB).

The restoration process was conducted with the principle of authenticity, where original materials were preserved as much as possible. Now, Tangsi Belanda has been transformed into a premier historical tourist destination. The area's arrangement includes the construction of pedestrian paths, artistic lighting at night, and an information area explaining the historical chronology of the site. This area is now part of the Mempura "Heritage District," connected by a magnificent bridge to the city center of Siak.

Cultural and Educational Value

For the people of Siak, Tangsi Belanda Mempura is not just a monument of defeat, but a reminder of the long struggle to regain sovereignty. Culturally, this site contributes to Siak's identity as a "Heritage City" in Indonesia. Its existence provides visual lessons for the younger generation about past construction techniques and how colonial urban planning was designed.

This site is often used as an educational location for students and history researchers. The uniqueness of its historical facts, such as the existence of underground tunnels rumored to reach the riverbank, continues to be an attraction for tourists who enjoy historical mysteries. Tangsi Belanda Mempura now stands tall, no longer as a symbol of oppression, but as a cultural asset that enriches the historical narrative of the Nusantara in the Malay land.
