A little history of Quimper ramparts
Quimper is the capital city of Breton Cornwall: the city was surrounded by walls in the beginning of the 13th century. They extended it in 1380 and rebuilt it in the 15th century.
The duke Pierre II of Brittany was allowed in 1452 to raise a kind of fortress to the forefront of the confluence.
In the 16th century, the wall bordered the left bank of river Steir. To the East, the wall went along the cathedral's chevet: there were 5 gates and several towers, Bihan's tower included.
