Between 1993 and 1996, several archaeological excavation campaigns at the site of Las Eretas partially unearthed the urban fabric of a fortified village from the Early Iron Age, the most significant structural remains of which included the wall and towers that defended it, and several dwellings built around a street and public square which facilitated pedestrian traffic inside the fortress.
The protohistoric village with its houses dates from the 6th to the 4th centuries BC and are typical of the Urnfield culture. Today there is a museum where thematic areas have brief text with illustrations – maps, photographs and drawings –, and a display cases showing original archaeological pieces, both from the Las Eretas site and other Navarrese Iron Age villages which have been investigated.
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.
