In the Roman period, Csepel Island occupied a transitional position along the Danube frontier. Although geographically located on the eastern edge of
Pannonia, neither archaeological evidence nor written sources suggest that it formed an integrated part of the province. Roman-period finds on the island—primarily pottery, brooches (fibulae), and coins—occur sporadically and are concentrated mainly along the riverbanks, without forming any discernible settlement pattern. In contrast, the opposite bank of the Danube was lined with a chain of limes fortifications, including Campona, Matrica, and Vetus Salina, which played a key role in controlling river crossings. Based on the available evidence, the island was probably a sparsely used border zone where contacts took place between the Roman world and the populations living east of the river, including the Sarmatian
Iazyges. During the
Hungarian conquest of the Carpathian Basin (: "conquest of the homeland"), Csepel Island became the early homestead of
Árpád's tribe. The island is named after Árpád's
horse groom, Csepel. It features Hungary's tallest structure,
Lakihegy Tower, a radio mast used today intermittently for power network control purposes. ==References==
