Terramare, Terramara, or Terremare is a technology complex mainly of the central Po valley, in Emilia-Romagna, Northern Italy, dating to the Middle and Late Bronze Age ca. 1700–1150 BC. It takes its name from the "black earth" residue of settlement mounds. Terramare is from terra marna, "marl-earth", where marl is a lacustrine deposit. It may be any color but in agricultural lands it is most typically black, giving rise to the "black earth" identification of it. The population of the terramare sites is called the terramaricoli. The sites were excavated exhaustively in 1860–1910.
