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:
The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
