The Warre hive (sometimes called the vertical top bar hive) is named after a French abbot who developed a simple hive that could easily be constructed by the common Joe.
Hives, also called urticaria, are circumscribed swellings on the skin that often are itchy. Often they are pink or red, but they don't have to be. Hives happen when the cells in the skin called mast cells release histamine, a chemical that causes tiny blood vessels (capillaries) to leak fluid. When this leaking fluid accumulates in the skin, it forms the swellings that we recognize as hives.
