Earlier, Japan Holes built for storage of supplies and equipment War the Japanese army, with the length of the tunnel which reaches 1400 m and winding and has a width of about 2 meters. There are a number of special rooms in this tunnel, among them the space reconnaissance, ambush room, jail, and armory.
In addition to its strategic location in the city which was once the seat of government of Central Sumatra, ground into the walls of the tunnel is a type of soil that when mixed with water will be more robust. Even the earthquake that rocked West Sumatra in 2009 and not much damage the structure of the tunnel.
It is estimated that tens to hundreds of thousands of forced labor or romusha deployed on the island of Java, Sulawesi and Kalimantan to dig this tunnel.
