The oldest monument of Boulogne-sur-Mer was built in three stages, in the 12th, 13th and 18th centuries. In fact, this belfry was originally a seigniorial prison, transferred to the community in 1230. 38 years later, Saint-Louis ordered the destruction of the tower’s second floor, as well as of the community’s charter of freedom and the town’s seal, as it was refusing to pay a tax on the eighth crusade. One year later, the town, its privileges restored, was able to rebuild the missing part. As for the last octagonal level, it was built in 1734, after the spire was burnt.
Today the belfry is one of 56 in northeastern France and Belgium with shared UNESCO World Heritage Site status and serves as the home to a museum of Celtic remains from the Roman occupation.
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.
