Stilt houses are houses raised on stilts over the surface of the soil or a body of water. Stilt houses are built primarily as a protection against flooding; they also keep out vermin. The shady space under the house can be used for work or storage. Stilt houses are commonly found in Southeast Asia, Oceania, Central America, Caribbean, northern parts of South America, Madagascar, Mauritius, Seychelles and the Maldives.

Terramare, terramara, or terremare is a technology complex mainly of the central Po valley, in Emilia, Northern Italy, dating to the Middle and Late Bronze Age c. 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.
