Built in 1631 by the celebrated architect François Mansart (1598-1666) at the request of Jean de Choisy, the Château de Balleroy and its surrounding buildings are one of the first urban plans that inspired other chateaux, including Versailles. All the buildings were built from scratch. The chateau itself has retained almost all of its original features and it is because of this that it witnessed the major innovations of the 17th Century.
In 1970, Malcolm S. Forbes, owner of a major U.S. newspaper group acquired the chateau which was then fully restored and refurbished. Today, his four sons and his daughter continue his work.
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.
