Bagacum (Today Bavay) was an Roman city and remarkable remains of ancient forum still exist. The 2,5 hectare are contains ruins of a central esplanade, temple and cryptoporticus (covered corridor or passageway).
The birth of Bavay after the conquest was the result of the reorganization of the territory by Augustus (probably between 16 BC and 13 BC). The town became the capital for the Nervii under the name of Bagacum and was an important junction of seven roads, the meeting-place of which was marked by a milestone, destroyed in the 17th century and replaced in the 19th century by a column.
From the Claudian period and especially under the Flavians in the late 1st century the city grew. Large monuments were built: a forum, thermal baths fed by an aqueduct bringing water from a fountain near Floursies located twenty kilometres away, and other buildings with a seemingly official nature adorned the city.
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.
