Sumba in the context of "Sumbawa"

A dolmen (/ˈdɒlmɛn/), or portal tomb, is a type of single-chamber megalithic tomb, usually consisting of two or more upright megaliths supporting a large flat horizontal capstone or "table". Most date from the Late Neolithic period (4000–3000 BCE) and were sometimes covered with earth or smaller stones to form a tumulus (burial mound). Small pad-stones may be wedged between the cap and supporting stones to achieve a level appearance. In many instances, the covering has eroded away, leaving only the stone "skeleton".

In Sumba (Indonesia), dolmens are still commonly built (about 100 dolmens each year) for collective graves according to lineage. The traditional village of Wainyapu has some 1,400 dolmens.

The Lesser Sunda Islands (Indonesian: Kepulauan Sunda Kecil, Tetum: Illá Sunda ki'ik sirá, Balinese: ᬓᬧᬸᬮᭀᬯᬦ᭄ᬲᬸᬦ᭄ᬤᬘᬾᬦᬶᬓ᭄, romanized: Kapuloan Sunda cénik), now known as Nusa Tenggara Islands (Indonesian: Kepulauan Nusa Tenggara, or "Southeast Islands"), are an archipelago in the Indonesian archipelago. Most of the Lesser Sunda Islands are located within the Wallacea region, except for the Bali province which is west of the Wallace Line and is within the Sunda Shelf. Together with the Greater Sunda Islands to the west, they make up the Sunda Islands. The islands are part of a volcanic arc, the Sunda Arc, formed by subduction along the Sunda Trench in the Java Sea. In 1930 the population was 3,460,059; today over 17 million people live on the islands. Etymologically, Nusa Tenggara means "Southeast Islands" from the words of nusa which means 'island' from Old Javanese language and tenggara means 'southeast'.

The main Lesser Sunda Islands are, from west to east: Bali, Lombok, Sumbawa, Flores, Sumba, Savu, Rote, Timor, Atauro, Alor archipelago, Barat Daya Islands, and Tanimbar Islands. Apart from the eastern half of Timor island and Atauro island which constitute the nation of Timor Leste, all the other islands are part of Indonesia.

The Australasian realm is one of eight biogeographic realms that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas.

The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the Oceanian realm.

Wallacea /wɒˈleɪsiə/ is a biogeographical designation for a group of mainly Indonesian islands separated by deep-water straits from the Asian and Australian continental shelves. Wallacea includes Sulawesi, the largest island in the group, as well as Lombok, Sumbawa, Flores, Sumba, and Timor. The islands of Wallacea lie between the Sunda Shelf (the Malay Peninsula, Sumatra, Borneo, and Java) to the west, and the Sahul Shelf, including Australia, New Guinea, and Maluku islands to the south and east. The total land area of Wallacea is 347,000 km (134,000 sq mi).

Waiyapu is a traditional village (desa) on Sumba island, East Nusa Tenggara province, Indonesia.

It has some 1,400 dolmens - one of the highest concentrations of these megaliths on Sumba.

Flores is one of the Lesser Sunda Islands, a group of islands in the eastern half of Indonesia. Administratively, it forms the largest island in the East Nusa Tenggara Province. The area is 14,250 km. Including Komodo and Rinca islands off its west coast (but excluding the Solor Archipelago to the east of Flores), the population was 1,878,875 in the 2020 Census (including various offshore islands); the official estimate as of mid-2024 was 2,014,110. The largest towns are Ende and Maumere. The name Flores is of Portuguese origin, meaning "Flowers".

Flores is located east of Sumbawa and the Komodo Islands, and west of the Solor Islands and the Alor Archipelago. To the southeast is Timor. To the south, across the Sumba Strait, is Sumba Island, and to the north, beyond the Flores Sea, is Sulawesi.

Savu (Indonesian: Sawu, also known as Sabu, Havu, and Hawu) is the largest of a group of three islands, situated midway between Sumba and Rote, west of Timor, in Indonesia's eastern province, East Nusa Tenggara. Ferries connect the islands to Waingapu on Sumba, Ende on Flores, and Kupang in West Timor. Flying to Savu through Susi Air from Kupang, Ende, and Waingapu is also possible.

East Nusa Tenggara (Indonesian: Nusa Tenggara Timur; NTT; Indonesian pronunciation: [ˌnusa təŋˌɡara ˈtimʊr], lit. 'East Southeast Islands') is the southernmost province of Indonesia. It comprises the eastern portion of the Lesser Sunda Islands, facing the Indian Ocean in the south and the Flores Sea in the north, with a total land area of 47,238.07 km. It consists of more than 500 islands, with the largest ones being Sumba, Flores, and the western part of Timor; the latter shares a land border with the separate nation of East Timor. The province is subdivided into twenty-one regencies and the regency-level city of Kupang, which is the capital and largest city.

Archaeological research shows that Liang Bua cave in East Nusa Tenggara has been inhabited by humans since about 190,000 years ago. The site was home to early humans, including Homo floresiensis, who were found in the cave's archaeological layers.
