Almost all TSG sites are located within five kilometres of each other and are aligned along a river corridor formed by the Tisza and the Danube. They served as an important centre of innovation in prehistoric Europe and formed a major network hub for the region at a time when Mycenaean, Hittite and New Kingdom Egypt was at its peak around 1500-1200 BC. The vast majority of sites were founded between 1600 and 1450 BC, and virtually all of them fell into decline around 1200.
