From Wikipedia: The Coldstream Guards is the oldest regiment in the Regular Army in continuous active service, originating in Coldstream, Scotland in 1650 when General George Monck founded the regiment. It is one of two regiments of the Household Division that can trace its lineage to the New Model Army, the other being the Blues and Royals (Royal Horse Guards and 1st Dragoons).
