Term used in North American archaeology to describe a group of sites in the middle Ohio River valley, particularly in southern Ohio and northern Kentucky, most of which date to the halfmillennium following 500 BC. The best-known sites are earthen mounds, many of which have a distinctive conical shape, and other earthworks. Many mounds were built over places where one or more large, special-purpose structures were previously located. The mounds were built gradually through the addition of graves and layers of earth. They contain different kinds of graves, including loglined tombs with skeletons and valued artefacts, such as copper bracelets. Adena mounds were often built in prominent places, presumably serving as important landmarks for nearby dispersed populations.
