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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
