Gua Belanda is a manmade tunnel complex located within the Taman Hutan Raya Juanda forest park in North Bandung. Originally constructed by the Dutch colonial government in 1918, the site served as a vital radio communication center and bunker for the Royal Netherlands East Indies Army (KNIL). The tunnel system extends approximately 144 meters and features several chambers once utilized as barracks, interrogation rooms, and command posts. During the colonial era, it functioned as a strategic military outpost before being used by the Indonesian military after independence. The interior is characterized by damp, dark concrete walls and heavy steel doors that reflect its utilitarian military history. It is situated in a protected conservation forest, meaning it is surrounded by native highland vegetation. The site remains a tangible remnant of the military infrastructure maintained by the Dutch in the West Java region. Visitors can explore the cavernous interior, which still retains portions of its original layout.
