The greatest number of dolmens are around Madaba, like the ones at Al Faiha village, 10 km (6.2 mi) to the west of Madaba city. In northern Somalia, the town of Aw Barkhadle, named in honour of the 13th century scholar and saint Yusuf bin Ahmad al-Kawneyn, is surrounded by a number of ancient structures.In Turkey, there are some dolmens in the Regions of Lalapasa and Suloglu in the Province of Edirne and the Regions of KOfcaz, Kirklareli and Demirkoy in the Province of Kirklareli, in the Eastern Thrace. Among these are dolmens, burial mounds, menhirs (standing stones), and stelae.Dolmens are known by a variety of names in other languages, including Irish: .

) is a type of single-chamber megalithic tomb, usually consisting of two or more vertical megaliths supporting a large flat horizontal capstone ("table"), although there are also more complex variants. Dolmens were typically covered with earth or smaller stones to form a tumulus.
In many instances, that covering has weathered away, leaving only the stone "skeleton" of the burial mound intact.
In northern Tunisia, Dougga is an important ancient site, which contains a necropolis with dolmens.
The settlement also features a sanctuary dedicated to Ba'al Hammon, neo-Punic stelae, the mausoleum, architectural fragments, and a temple dedicated to Masinissa, the remains of which were found during archaeological excavations.
They consist of a kerb surrounding an oval mound, which covered a rectangular chamber of stones with the entrance on one of the long sides.
Some have a more complex layout and include an entrance passage giving them a T-shape.
Archaeologists still do not know who erected these dolmens, which makes it difficult to know why they did it.
