Megalithic in the context of "Ganghwa Island"

A trilithon or trilith is a structure consisting of two large vertical stones (posts) supporting a third stone set horizontally across the top (lintel). It is commonly used in the context of megalithic monuments. The most famous trilithons are those of Stonehenge in England.

The word trilithon is derived from Ancient Greek τρι- (tri-), meaning "three", and λίθος (líthos), meaning "stone", and was first used in its modern archaeological sense by William Stukeley.

Domus de Janas (Sardinian for 'House of the Fairies' or, alternatively, 'House of Witches') are a type of pre-Nuragic rock-cut chamber tomb found in Sardinia. They consist of several chambers quarried out by the people of the San Ciriaco through Ozieri cultures and subsequent cultures, resembling houses in their layout.

Built mostly between 3400 and 2700 BC, they date to the late Neolithic, Chalcolithic and early Bronze Age, including the Bell Beaker period. A necropolis of them at the site of Anghelu Ruju, near Alghero, consists of 38 tombs. Other large sites are those of Montessu, near Villaperuccio, and of Sant'Andrea Priu at Bonorva. Many other domus de janas can be found throughout the island, with the exception of Gallura (where the deceased were usually buried in megalithic circles, such as that those of Li Muri).

Tarxien (Maltese: Ħal Tarxien [ˈħɐl tɐrˈʃɪːn]) is a town in the Port region of Malta, seat of the Port Regional Council. Its population stood at 8,583 in March 2014.

The town is most notable for the Tarxien Temples, a megalithic temple complex which is among the oldest freestanding structures on Earth. It forms part of a UNESCO World Heritage Site.

Mnajdra (Maltese: L-Imnajdra) is a megalithic temple complex found on the southern coast of the Mediterranean island of Malta. Mnajdra is approximately 497 metres (544 yd) from the Ħaġar Qim megalithic complex. Mnajdra was built around the fourth millennium BCE; the Megalithic Temples of Malta are among the most ancient religious sites on Earth, described by the World Heritage Sites committee as "unique architectural masterpieces." In 1992, UNESCO recognized the Mnajdra complex and four other Maltese megalithic structures as UNESCO World Heritage Sites. In 2009, work was completed on a protective tent.

The Skorba temples are megalithic remains on the northern edge of Żebbiegħ, in the Northern Region of Malta, which have provided detailed and informative insight into the earliest periods of Malta's neolithic culture. The site was only excavated in the early 1960s, rather late in comparison to other megalithic sites, some of which had been studied since the early 19th century. The site's importance has led to its listing as a UNESCO World Heritage Site, a listing it shares with six other megalithic temples in Malta.

This later excavation allowed the use of modern methods of dating and analysis. The temple itself is not in good condition, especially in comparison to the more complete temples of Ħaġar Qim and Tarxien. However, the importance of this site does not lie in the actual remains but rather in what was garnered from their excavation.

The Coolera Peninsula (Irish: Cúil Iorra) is a peninsula in Sligo Bay, County Sligo, Ireland. It is the most populous of County Sligo's peninsulas, and the second-largest by land area. The primary population centres on Coolera are the coastal town of Strandhill on its western shore, and Magheraboy, a suburb of Sligo town.

The peninsula is characterised by a vast network of Megalithic and Neolithic tombs, cairns and ringforts spread out across its landscape. The Carrowmore Megalithic Complex dates back to the 4th millennium BC, and is one of the largest megalithic complexes in Ireland. The 30,000-tonne tomb of Queen Médb, known as Miosgán Médhbh, sits atop Knocknarea mountain and is clearly visible from much of northern Sligo. Taken together, Sligo County Council has applied for this network of ancient monuments to be recognised as a UNESCO World Heritage Site.

Carrowmore (Irish: An Cheathrú Mhór, 'the great quarter') is a large group of megalithic monuments on the Coolera Peninsula to the west of Sligo, Ireland. They were built in the 4th millennium BC, during the Neolithic (New Stone Age). There are 30 surviving tombs with another 25 which have been destroyed since 1800, making Carrowmore one of the largest clusters of megalithic tombs in Ireland, and one of the 'big four' along with Carrowkeel, Loughcrew and Brú na Bóinne. Carrowmore is the heart of an ancient ritual landscape which is dominated by the mountain of Knocknarea to the west. It is a protected National Monument.

It is quite difficult to define Indonesian art, since the country is immensely diverse. The sprawling archipelago nation consists of 17,000 islands. Around 922 of those permanently inhabited, by over 600 ethnic groups, which speak more than 700 living languages.

Indonesia also has experienced a long history, with each period leaves distinctive art. From prehistoric cave paintings and megalithic ancestral statues of Central Sulawesi, tribal wooden carving traditions of Toraja and Asmat people, graceful Hindu-Buddhist art of classical Javanese civilization which produced Borobudur and Prambanan, vivid Balinese paintings and performing arts, Islamic arts of Aceh, to contemporary arts of modern Indonesian artists. Both Indonesian diversity and history add to the complexity of defining and identifying what is Indonesian art.
