Nangasia Site

Exploring the Traces of Maritime and Megalithic Civilization at Nangasia Site, Dompu

Nangasia Site is one of the most significant archaeological assets in Dompu Regency, West Nusa Tenggara. Located in the coastal area of Marada Village, Hu'u District, this site holds a long narrative about the cultural transition of the people of East Sumbawa, from megalithic traditions to the early Islamic influences in the region. Nangasia's uniqueness lies in the blend of its geographical character on the coastline with rock structures that indicate the complex social life of past communities.

Historical Origins and Periodization

Chronologically, Nangasia Site is estimated to have been a human settlement center at least since the proto-historic period until the ancient Dompu Kingdom era. Based on findings of ceramic fragments and rock structure patterns, archaeologists conclude that this site reached its peak between the 14th and 17th centuries AD.

The name "Nangasia" itself in the local language refers to its geographical condition—"Nanga" means estuary or river, and "Asia" is often associated with a local term for a specific type of vegetation or water condition. Its strategic location on the southern coast of Dompu indicates that Nangasia was once an ancient port or an important contact point in the Nusantara maritime trade route, connecting the inland areas of Dompu with the spice and sappanwood trade network, which were the region's leading commodities in the past.

Architectural Style and Construction Details

The main characteristic of Nangasia Site is the use of natural stones arranged without modern cement adhesive, relying instead on specific gravity locking techniques and precise stacking. At this site, building structures resembling terraced mounds and remnants of permanent buildings made of andesite and coral stones have been found.

One of the most prominent architectural elements is the presence of ancient graves with stone tombstones featuring distinctive carvings. Unlike graves in Java or Sumatra from the same period, the tombstones at Nangasia show a stylistic blend (syncretism) between prehistoric local motifs and early Islamic ornamental influences. The shape of the tombstones found often resembles a "gada" or cylinder with simple geometric decorations, reflecting the social status of the buried individual. The site's layout facing the sea also suggests that the people of Nangasia had a strong cosmological orientation towards water elements.

Historical Significance and Important Events

Nangasia Site is tangible proof that Dompu was not merely an agricultural region but a formidable maritime power. The significance of this site is closely related to the religious transition events in the Sumbawa region. Nangasia is suspected to have been one of the entry points for Islamic preachers from the Makassar and Gresik regions before spreading to the administrative center of the Dompu Kingdom.

Furthermore, Nangasia's existence is linked to the resilience of local communities against natural disasters. Given its location on the southern part of Sumbawa Island, this site is a silent witness to the various volcanic activities of Mount Tambora in the past. Although buried by volcanic ash material in several soil layers, Nangasia's basic structure has survived, providing important data for researchers on how coastal settlements responded to major geological disasters.

Figures and Connection with the Dompu Kingdom

In local historical records (Bo' Sangaji Kajao), the Nangasia area is often associated with local figures who served as rulers of coastal areas or "Ncuhi." Before the unification of small kingdoms under the banner of the Dompu Kingdom, this region was ruled by independent Ncuhi. Nangasia was most likely the center of power for one of the Ncuhi who controlled sea access.

The connection of this site with the Dompu Sultanate is evident in the burial styles. Some graves are believed to belong to nobles or religious scholars tasked with guarding the border areas and trade routes in the south. The presence of these figures ensured that the flow of sappanwood trade—highly sought after by Europeans and Chinese in the 16th century—ran smoothly through the small ports around Nangasia.

Cultural and Religious Importance

For the people of Marada Village and its surroundings, Nangasia is not just a pile of inert stones. This site is considered a sacred place (Dana mboha) with spiritual value. To this day, traces of megalithic culture are still felt in the form of ancestor veneration performed around the site.

The presence of ancient tombstones also serves as a religious identity for local residents, affirming their very old Islamic roots. The integration of the tradition of venerating large stones (megalithic) with Islamic prayers in customary ceremonies around Nangasia demonstrates how flexible Dompu culture is in absorbing external influences without losing its original identity.

Preservation Status and Restoration Efforts

Currently, Nangasia Site is under the supervision of the Cultural Preservation Center (BPK) Region XV. The main challenges in preserving this site are natural factors, especially coastal abrasion and the growth of wild vegetation that can damage stone structures. Additionally, human activities such as illegal digging by treasure hunters in the past have damaged some parts of the tomb structures.

Restoration efforts have been carried out gradually through archaeological excavations aimed at remapping the original extent of the site. The Dompu Regency government has also begun promoting Nangasia as a historical tourism destination to support the tourism sector in Hu'u District, which has been more known for surfing.

The construction of boundary fences and historical information boards are initial steps to ensure that Nangasia's historical values are preserved and can be learned by future generations.

Unique Facts of Nangasia Site

One rarely known unique fact is that around Nangasia Site, fragments of ancient glass and beads originating from outside the Nusantara are often found. This strengthens the theory that Nangasia was once a meeting point of international cultures. Furthermore, the stone-laying technique on the wall structures at Nangasia bears similarities to the structural patterns at archaeological sites in the Pacific region, indicating a very broad Austronesian cultural connection.

In conclusion, Nangasia Site is a living monument that tells the story of Dompu's past glory. It is a meeting point between land and sea, between ancient traditions and new values, and between human resilience and the power of nature. Through sustainable preservation, Nangasia will continue to be a window for the world to see the depth of civilization on Sumbawa Island.
