Plural of glen; narrow valleys, especially those found in mountainous or hilly regions, particularly in Scotland and Ireland.
From Gaelic 'gleann' (valley). The word entered English from Celtic languages and has been used for centuries to describe the distinctive geographical features of the British Isles.
Scotland has over 100 named glens, and they were so important to Highland culture that entire clans would be identified by which glens they inhabited—your glen was your identity!
