Marapu: Sumba's ancestral religion explained
What Marapu is, how it shapes Sumbanese houses, tombs, funerals and the Pasola, and how visitors can show respect.
To understand Sumba you need to understand Marapu. It is the island's ancestral belief system, and it explains why the houses look the way they do, why huge stones are dragged across the island and why the Pasola exists.
The basics
Marapu is the belief that the spirits of ancestors watch over the living and act as intermediaries with a supreme creator. Keeping a good relationship with them through rituals, offerings and respect for custom (adat) brings harmony, good harvests and health. Ritual specialists, often called rato, lead the ceremonies.
The house as a sacred map
A traditional Sumbanese house has three levels. Animals live below, people in the middle and the tall roof is reserved for the ancestors, heirlooms and sacred objects. That is why the roofs of villages like Ratenggaro and Wainyapu rise so high.
Stone tombs and funerals
The dead are buried in stone tombs in the village square, close to the living. Dragging a large slab can involve hundreds of people and long ceremonies, and funerals can last for days, with buffalo and pigs sacrificed. The horns and jaws you see on houses are records of these events. Some of the largest tombs are in Anakalang, at Pasunga and Gallubakul.
The Pasola
The Pasola, a ritual contest on horseback in western Sumba, belongs to the Marapu calendar and is linked to the arrival of sea worms (nyale) on the shore. Read our Pasola guide.
How to show respect
- Never touch, sit on or climb stone tombs or sacred objects.
- Ask before entering a house or photographing ceremonies.
- Accept betel nut (sirih pinang) if offered, even if you only hold it; it is a sign of welcome.
- Follow your guide's lead at funerals and rituals.
Marapu in daily life
Marapu shapes the layout of villages, the form of the houses, the stone tombs and the calendar of rituals, including the Pasola. Many Sumbanese are Christian and also follow Marapu customs. See traditional houses, megalithic tombs and horses in Sumba.
As a visitor
Be respectful at ceremonies, ask before taking photos and follow your guide. Read village etiquette.
