A family named Guilguiffin appears in the annals of the area, but seems to die out in the 14th century. Guilllaume De Ty Varlen settled at Guilguiffin and had a significant fortified residence. Jean Louis Armand Fortuné De Plouec, born in 1694, replaced the ancient manorr with the current chateau between 1750 and 1760, using plans drawn up by the Quimper architect Nicolas Pochic. In 1797 the donjon, a lead-capped tower in the middle of the chateau, was razed. In 1847, 4 years later, the chapel collapses but is rebuilt within the same year. In 1965, the chateau was in desolate condition. In 1967, Philippe Davy immediately begins restoration of the property. Today Château de Guilguiffin provides accomodation services.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
