Table of Contents


Located in the shadow of the mighty Mount Merapi in Yogyakarta, Indonesia, Bunker Kaliadem stands as a silent witness to the volcano’s devastating power. This concrete bunker, originally built as a safe haven during volcanic eruptions, has now become a popular tourist attraction, offering a poignant reminder of the 2006 eruption and the unstoppable force of nature.

The History of Bunker Kaliadem:

Bunker Kaliadem, also known as the Merapi Bunker, was constructed in 2001 as a shelter for residents and researchers during volcanic eruptions. Situated approximately 4 kilometers from the peak of Mount Merapi, the bunker was designed to withstand the heat and pressure of pyroclastic flows – fast-moving currents of hot gas and volcanic matter.

However, during the 2006 eruption of Mount Merapi, the bunker proved tragically insufficient. Two volunteers who took refuge in the bunker were killed by the intense heat of the pyroclastic flows, their bodies found huddled together in the back of the shelter. This tragic event highlighted the unpredictability and immense power of Mount Merapi.

Visiting Bunker Kaliadem:

Today, Bunker Kaliadem serves as a stark reminder of the risks and dangers associated with living in close proximity to an active volcano. Visitors can explore the bunker, which has been left largely as it was following the 2006 eruption. The scorched walls and the eerie quiet inside the bunker offer a chilling glimpse into the terrifying experience of being caught in a volcanic eruption.

The bunker is often included as a stop on the Lava Tour Merapi, a popular off-road tour that takes visitors around the slopes of Mount Merapi. From the bunker, visitors can also enjoy panoramic views of Mount Merapi and the surrounding landscape, which bears the scars of past eruptions.


Bunker Kaliadem is more than just a tourist attraction; it’s a monument to human resilience in the face of nature’s fury. It serves as a reminder of the destructive power of volcanoes and the human toll of natural disasters. A visit to Bunker Kaliadem offers a sobering but important perspective on the relationship between humans and the natural world, making it a must-visit for anyone traveling to Yogyakarta.
