The Barbican, the 15th century bastion with a circular floor plan used to belong to the wall system of the Bishop's Castle. Its construction is linked to the visit of General Pál Kinizsi, who came to the town in 1498. In the shadow of the Turkish threat the defence systems of castles and towns were strengthened all around the South. The Gothic-style gate tower was built in the 15th century at the western corner of the high castle wall. The Barbican is a round gate tower sitting on a narrow column. Its back gate served a specific purpose: it enabled the defenders to attack the attacking enemy getting in the gate from the side. The Barbican is surrounded with the remains of the castle ditch and you can walk up to the entrance on the old drawbridge. The pulleys of the drawbridge are still displayed inside.
There is a fantastic view opening towards the town from the top of the bastion. You can walk along the machicolation (the wooden walkway) on the top of the Barbican.
After defence structures became obsolete during the 18th-19th century, similarly to other parts of the town, houses were built around the castle wall. The buildings that were built along the castle walls were demolished in the 1960s making the old Barbican as well as other parts of the wall free and visible again.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
