The earliest recorded castle of Château de Challain-la-Potherie dates all the way back to the medieval age in 1050. The original castle was probably part of the ‘Les Marches de Bretagne’ a series of fortresses that acted as a defensive line that protected the people of the ancient region of France known as Brittany. That chateau, and many others that followed it were destroyed in the wars, and conflicts that wracked the area in the centuries that followed.
The current Château de Challain-la-Potherie was built from 1847 to 1854 in the neo-Gothic style, which was fashionable among the French aristocracy at the time. Its architect, René Hodé, designed many other châteaux in the same style in Anjou, but Challain remains the most imposing.
The 19th-century castle was commissioned by Louise-Ida de La Potherie, the last of her name, and her husband, the Count of La Rochefoucauld-Bayers. The choice of the neo-Gothic style was a means for them to restore the family's glory after the French Revolution. It was also a choice motivated by the tastes of the time, as neo-Gothic was in vogue among the Angevin aristocracy. René Hodé specifically adopted the troubadour style, which applied a neo-medieval decoration to a functional structure. The internal structure of the castle and its general layout followed the neoclassical architectural rules developed in the 18th century.
Despite its grandeur and significant place in the history of Angevin architecture, it suffered some degradation after the death of its patrons. It had numerous successive owners during the 20th century and served as a vacation colony center for about twenty years. Finally, in 2002, it was transformed into a luxury guesthouse.
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.
