Angers castle is a 13th century fortress perched on a rocky promontory over-looking the Maine. Inside its ramparts, structures dating from the 14th, 15th and 18th centuries permit visitors to see how the castle evolved over the years. The earliest signs of human occupation of the site in fact date back 4,000 years. The counts of Anjou first built a stronghold here in the 9th century to defend themselves against the attacking Normans. Of this structure only the two side walls of the great hall, including a 12th century door, plus the apse of the chapel of Saint Laud, now remain.
Following the expulsion of the Plantagenets by Philippe Auguste, in 1230 the young Saint-Louis began building an enormous fortress of some 2000 m² around the old counts' stronghold to defend his realm against the threat posed by the neighbouring duchy of Britany. This construction was flanked by 17 towers and had only two doors, a town door and a country door. In 1360, the dukes of Anjou started to erect new buildings inside the fortress, including the Royal Lodge, the chapel, and the inner castle.
