Belkoain is a megalithic dolmen in Andoain, in the province of Guipuscoa in the Basque Country, Spain. It stands in a mountain pass on Belkoain at an altitude of 465 m. The site forms part of the megalithic station of Andatza and is classified as a site of cultural interest.
The dolmen has collapsed, and its mound is now much deformed. It measures 11 m in diameter, with a height of 1,60 m to the north and 1 m to the south. A hollow to the south exposes several detached orthostats that once formed the burial chamber. The monument was built from local sandstone.
The site was discovered by J. Eltuna and K. Mariezkurrena in 1978 and has not been excavated. It has been associated with the Neolithic, Copper Age and Bronze Age. Its estimated date is 4000 BCE to 3000 BCE, based on typological comparison.
Spain has many megalithic tombs. The country’s dolmens extend from Andalusia in the south to Galicia in the north-west. Some of the finest are at Antequera in Andalusia, where the Dolmen of Menga, dated to about 3750 to 3650 BCE, is among Europe’s largest ancient megalithic structures.

Tradition and region
About this kind of monument
Dolmens of Andalusia, Extremadura and Galicia
Spain has a great many megalithic tombs, and the Atlas's Spanish dolmens run from Andalusia in the south to Galicia in the north-west. The finest are at Antequera in Andalusia, where the Dolmen of Menga, dated to about 3750 to 3650 BCE, is among the largest ancient megalithic structures in Europe. It is 27.5 metres long, 6 metres wide and 3.5 metres high, built with thirty-two megaliths, the largest weighing about 180 tonnes. After the chamber was finished it was covered with soil and built up into the hill seen today; when it was opened in the nineteenth century archaeologists found the skeletons of several hundred people. The Dolmen of Viera stands 70 metres away, and the tholos of El Romeral lies about 4 kilometres off; the three were inscribed as the Antequera Dolmens Site, a UNESCO World Heritage Site, in 2016.
In the south-west, the Dolmen de Soto at Trigueros in Huelva province is a Neolithic tomb estimated to date between 3000 and 2500 BCE, one of about 200 Neolithic burial sites in the province. It was found in 1922 when its owner, Armando de Soto Morillas, wanted to build a house; the German archaeologist Hugo Obermaier found eight bodies in a fetal position with artefacts, and its engraved and painted uprights have been studied more recently.
In Galicia and Portugal a dolmen is an anta, and in Catalan-speaking areas dolmens have folk names such as cova (cave), caixa (crate or coffin), taula (table) and arca (chest). These names are tradition: they record what people made of the monuments, not what they were built for.
When visiting Menga, look at the great capstones from inside the corridor, and at the way the mound was built up over the chamber.
