Located in a marshy area at the confluence of the Sieniocha with the Huczwa (tributary of the Western Bug), the early medieval settlement complex in Czermno included a stronghold and several settlements and cemeteries in its catchment, connected by a network of timber trackways. A major new development in the study of Czermno following many seasons of excavation (1940, 1952, 1974-1976, 1979, 1981, 1985, 1997) was brought by an international project implemented in 2011/2013 joined by several institutions enabled by government funding (Poland - NPRH, NCN, MKiDN; Germany - GWZO, Lepizig). The last decade has seen a comprehensive publication of findings from all past fieldwork in Czermno, and new excavation of some of the ramparts and suburb settlements. Given its likely identification with the stronghold of Cherven’ and its situation amidst marshy meadows (a setting highly promising for a range environmental), Czermno ought to become the key early medieval site in eastern Poland.
