The raised bank or embankment bordering a fen (a wetland area with waterlogged soil).
Compound of 'fen' (from Old English 'fenn' meaning marshy ground) and 'bank' (from Old Norse 'banki'). A simple descriptive geographical term combining two common English words.
Fenbankss were crucial to medieval English villages—these raised banks allowed people to build settlements and grow crops alongside dangerous marshlands, and many historic villages are still surrounded by the ghost-marks of ancient fen systems.
