The History and Significance of Barbicans in Medieval Europe

Barbican is a type of fortified outpost or gateway that was commonly used in medieval Europe, particularly in the British Isles. It was typically built at the entrance to a castle or walled town, and served as a defensive position to control access and protect against invaders.

A barbican was usually a small, fortified building or tower that projected out from the main wall of the castle or town, and was often surrounded by a moat or other water feature. It was designed to slow down or block the approach of enemy forces, and could be used as a strongpoint for archers or other defenders.

In some cases, barbicans were also used as a customs house or toll booth, where taxes and tolls were collected from travelers and traders entering the town or castle.

Today, the term "barbican" is sometimes used more broadly to refer to any fortified entrance or gateway, regardless of its location or size.
