At the tip of the Great Northern Peninsula of the island of Newfoundland, the remains of an 11th-century Viking settlement are evidence of the first European presence in North America. The excavated remains of wood-framed peat-turf buildings are similar to those found in Norse Greenland and Iceland.
Dating to around the year 1000 (carbon dating estimate 990-1050 CE), L'Anse aux Meadows is the only site widely accepted as evidence of pre-Columbian trans-oceanic contact. It is notable for its possible connection with the attempted colony of Vinland established by Leif Erikson around the same period or, more broadly, with Norse exploration of the Americas.
Today the area mostly consists of open, grassy lands; but 1000 years ago, there were forests which were beneficial in boat-building, house-building and for iron extraction. The remains of eight buildings were located. They are believed to have been constructed of sod placed over a wooden frame. Based on associated artifacts, the buildings were variously identified as dwellings or workshops.
L'Anse aux Meadows was named a World Heritage site by UNESCO in 1978.
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.
