Dieppe
First recorded as a small fishing settlement in 1030, Dieppe was an important prize fought over during the Hundred Years' War.
Dieppe housed the most advanced French school of cartography in the 16th century. Two of France's best navigators, Michel le Vasseur and his brother Thomas le Vasseur, lived in Dieppe when they were recruited to join the expedition of René Goulaine de Laudonnière which departed Le Havre for Florida on April 20, 1564. The expedition resulted in the construction of Fort Caroline, the first French colony in the New World. Another expedition two years before where Goulaine de Laudonnière was under command of Jean Ribault, a local Huguenot captain, had resulted in the foundation of Charlesfort, now in South Carolina. Dieppe was the premier port of the kingdom in the 17th century.
On July 23, 1632, 300 colonists heading to New France departed from Dieppe.
At the Revocation of the Edict of Nantes in 1685, Dieppe lost 3,000 of its Huguenot citizens, who fled abroad.
Roman Catholic Diocese of Quimper
There is evidence that Christianity was preached in Léon twenty years before the evangelization of Cornouaille, but ancient Breton chronology is very uncertain. The legend of St. Paul Aurelian, written in 884, shows that the Breton monks believed the See of Léon had been founded in the Merovingian epoch. The hermit Saint Ronan, a native of Ireland, often held to be one of the 350 bishops consecrated by Saint Patrick, was in the fifth century known as one of the apostles of Cornouailles and the neighbourhood around Léon. Paul Aurelian, a Gallic monk, founder of monasteries at Ouessant on the north-west coast of Brittany and on the Island of Batz, was believed to have founded in an abandoned fort a monastery which gave origin to the town of St. Pol de Léon, afterwards the seat of a diocese. He was the first titular of the see, a wonder-worker and prophet, and was held to have died in 575 at the age of 140 years, after having been assisted in his labours by three successive coadjutors. Though the monastery of Léon was probably founded by Paul Aurelian in the sixth century, the history of the diocese is more complicated. It is at least certain that there are traces in history of a Diocese of Léon as far back as the middle of the ninth century.
