Medan TourSahabatholidays.com – The horizon is dotted with dramatic, boat-shaped roofs that curve sharply upwards at both ends. These are the traditional Lake Toba houses, known locally as Rumah Bolon.
Every curve, every carving, and every color tells a story about life, death, and the relationship between humans and the divine. Many tourists ask: “What do these shapes mean?” or “Can I stay inside one of these Lake Toba houses?”
The answer is a resounding yes. Today, these houses serve as museums, living family homes, and even unique hotels for travelers seeking an immersive experience. Exploring these architectural wonders is a highlight of any trip to Samosir Island.
In this guide, Sahabat Holidays takes you on a journey through the wood and stone of Batak culture. We explore the meaning behind the design, the best places to see authentic villages, and how you can sleep inside a modern version of these legendary structures.
The Distinctive Look – Why the Buffalo Horns?
The most defining feature of Lake Toba houses is the roof. It curves deeply in the middle and rises to sharp points at the ends. Locals call this shape Gorga. It resembles the back of a water buffalo. In Batak culture, the buffalo is a symbol of strength, status, and agriculture. By designing their homes this way, the ancestors honored the animal that sustained their livelihood.
Interestingly, the shape also resembles a boat. Some anthropologists believe this honors the maritime journey of the ancestors who first migrated to Sumatra. Whether it represents a buffalo or a boat, the silhouette of a Rumah Bolon against the backdrop of the volcanic lake is one of the most photogenic sights in Indonesia.
A House of Three Worlds
A traditional Lake Toba house is never built directly on the ground. It stands on tall wooden stilts. This is not just to avoid floods or wild animals; it reflects the Batak ancient belief system (local religion Parmalim), which divides the universe into three layers.
- The Lower World (Banua Toru) – The space beneath the house, between the stilts, represents the underworld. Traditionally, families kept their livestock here—pigs, chickens, and buffaloes. The animals represent the earthly, primal needs of life.
- The Middle World (Banua Tonga) – The main living area, raised above the ground, represents the world of humans. This is where the family eats, sleeps, and gathers. To enter, you must climb a staircase and stoop low to pass through a small door. This design forces every guest to bow, showing respect to the owner of the house.
- The Upper World (Banua Ginjang) – The towering roof space represents the realm of gods and ancestors. It is considered sacred. Traditionally, families used this space to store heirlooms (pusaka) and sacred items, keeping them close to the heavens.

Where to See Authentic Lake Toba Houses
Not all houses you see today are old. Many are modern replicas. To see the authentic, ancient Lake Toba houses, you need to visit specific heritage villages. Sahabat Holidays includes these stops in our cultural tour packages.
1. Huta Bolon Simanindo Museum
This is the best-preserved complex on Samosir Island. It was formerly the home of King Sidauruk.
-
The Highlight – The complex features a massive main house surrounded by smaller structures. It is now a museum displaying Batak weapons, cooking utensils, and royal jewelry.
-
The Experience – Every morning, locals perform the Sigale-gale puppet dance right in front of these magnificent houses. It is the perfect photo opportunity.
2. Huta Siallagan (Ambarita)
Famous for its stone chairs, this village also features a row of beautifully painted Rumah Bolon.
-
The Context – seeing the King’s house directly behind the stone “courtroom” gives you a sense of how the legal and domestic lives of the royals intertwined.
3. Jangga Dolok Village
For travelers who want to see a “living” village rather than a museum, we take you to Jangga Dolok on the mainland (near Parapat).
-
The Reality – Here, regular families still live inside the traditional houses. You can see smoke rising from the roofs as they cook, and weavers working on the porches. It feels raw and authentic.
The Engineering Marvel – No Nails Used
One of the most surprising facts about traditional Lake Toba houses is their construction method. The ancestors built these massive structures without using a single metal nail.
-
Interlocking Wood – They used a sophisticated system of mortise and tenon joints (wooden pegs). The wood locks into place.
-
Fiber Ropes – They used Ijuk (black sugar palm fiber) to bind the roof and beams.
-
Earthquake Proof – This flexible construction allows the house to sway during earthquakes without collapsing. It is a brilliant example of ancient engineering adapting to the Ring of Fire.
Photography Tips for Architecture Lovers
Capturing the majesty of Lake Toba houses requires a bit of skill.
-
Go Wide – The roofs are wide and tall. Use a wide-angle lens or panorama mode to capture the full curve.
-
Look for Contrast – The best photos happen when the Red-Black-White house contrasts against the bright Blue sky or the Green hills.
-
Get Close – Don’t forget to take macro shots of the Gorga carvings to show the texture of the wood.
