Cornești-Iarcuri is the largest known Bronze Age fortress in Europe,[3] located in the immediate vicinity of the modern village of Cornești, between the Romanian cities of Arad and Timișoara.

Covering an area of 17.65 km2,[4] the site encompasses the remains of four enclosing rings of earthen ramparts, wooden palisades and moats.

[6] The site lies at the southeastern edge of the Mureș alluvial fan, part of the eastern Pannonian Basin.

[7] The fortification has four concentric enclosures intersected by the Pistrui valley to the south, which east of the village changes its name to Valea Luciului or Vâna Nerat.

Another hypothesis, supported by C. Răileanu in 1981, but refuted by Florin Medeleț, considered the ruins as the remains of the city of Tema,[8] mentioned in the Ravenna Cosmography.

It revealed that the Bronze Age fortress at Cornești was built by the Cruceni-Belegiš communities in the second half of the 2nd millennium BC.
