What is a "barbican"?

A barbican is a fortified outpost or gateway that serves as an additional line of defense for a castle or fortified town. Typically located in front of the main entrance, a barbican is designed to protect the gate and the walls from direct attacks. It often features defensive elements such as towers, walls, and arrow slits, allowing defenders to keep watch and engage enemies before they reach the main fortifications. The layout of a barbican can vary, but it usually includes a narrow passage that attackers must navigate, making them more vulnerable. Barbicans are common in medieval architecture, enhancing the security and complexity of fortifications while serving as a formidable barrier against potential invaders.
