The Château de Boulogne-sur-Mer was built in the 13th century by Philippe Hurepel (1180-1234), count of Boulogne and son of Philip II of France. Following the death of his half-brother, king Louis VIII after a short three-year reign, Hurepel was one of the leaders of a rebellion against the regent, Blanche de Castille, mother of the minor Louis IX. He constructed castles at Calais and Hardelot and refortified Boulogne. The castle is built in the eastern corner of the medieval walls surrounding the Haute Ville (literally, high town - the part of Bologne on the hill). The walls themselves were reconstructed by Hurepel. The eastern part of the castle was built over a corner of the Roman wall, parts of which are still visible in the basement. Housing together the political, legal and economic powers of the time, it was also a residential and defensive site.
Various modifications have taken place. Major alterations were carried out by the duc de Berry between 1394 and 1416. The horse shoe shape (barracks, arsenal) was completed around 1567. After being adapted because of developments in artillery during the 16th century, it lost some of its medieval character. In 1767, it became a barracks and, after World War II, it also housed a prison. In 1974, the town council took over ownership of the castle and decided to install its museum installations. Today the castle houses a Boulogne museum including exhibitions all around the world.
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.
