A new paper has been published about La Bastida, an impressive early Bronze Age city in Spain which may have been founded and settled by people from the Near East.

If someone has institutional access, perhaps you could report what, if anything is new since the information released in 2012.

This is the information from 2012.

The findings "indicate that La Bastida was probably the most powerful city of Europe during the Bronze Age and a fortified site since it was first built, in circa 2,200 BCE, with a defence system never before seen in Europe."

The fortification consisted of a wall measuring two to three metres thick, built with large stones and lime mortar and supported by thick pyramid-based towers located at short distances of some four metres. The original height of the defensive wall was approximately 6 or 7 metres. Until now six towers have been discovered along a length of 70 metres, although the full perimeter of the fortification measured up to 300 metres. The entrance to the enclosure was a passageway constructed with strong walls and large doors at the end, held shut with thick wooden beams.

"One of the most relevant architectural elements discovered is the ogival arched postern gate, or secondary door, located near the main entrance. The arch is in very good conditions and is the first one to be found in Prehistoric Europe. Precedents can be found in the second city of Troy (Turkey) and in the urban world of the Middle East (Palestine, Israel and Jordan), influenced by the civilisations of Mesopotamia and Egypt. This indicates that people from the East participated in the construction of the fortification. These people would have reached La Bastida after the crisis which devastated their region 4,300 years ago. It was not until some 400 to 800 years later that civilisations like the Hittites and Mycenaeans, or city-states such as Ugarit, incorporated these innovative methods into their military architecture."

"It also represents an innovation in the art of attacking and defending fortifications, especially on the military front. The construction was designed solely for military purposes, by people experienced in fighting methods unknown in those times to the West.

The towers and exterior walls denote advanced knowledge of architecture and engineering, with slopes of over 40 per cent. The lime mortar used offered exceptional solidity to the construction, strongly holding the stones and making the wall impermeable, as well as eliminating any elements attackers could hold on to.

The postern gate, as a hidden and covered entrance, demanded great planning of the defensive structure as a whole and of the correct engineering technique to fit it perfectly into the wall."

Another article from 2012:

"The fortification was not the only discovery made. From 2008 to 2011, excavations unearthed large residences measuring over 70 square metres distributed throughout the city's four hectares. These large houses and public buildings were alternated with other smaller constructions, all separated by entries, passageways and squares. A large pool held by a 20-metre dyke with a capacity for almost 400,000 litres of water also clearly denotes that the city's population was of a complexity and that it used advanced techniques incomparable to other cities of its time."

La Bastida seems to be part of the Argaric culture of Spain.
