A castle entrance gate with two towers, defended by a drawbridge and featuring two smaller gates for carriages and pedestrians, once led to Mordelles. This symbolic setting was where the future Dukes of Brittany swore an oath to defend Brittany's freedoms. The mediaeval walls to the west were built on the site of a third-century wall. An artillery platform was added on the fortified gateway (or barbican) to protect this entrance to Rennes.
