The current Jelling church was built of limestone around the year 1100. Archaeologists have found traces of three earlier wooden churches on the site. The first wooden church built on the site of the present edifice was the largest of its kind anywhere in Scandinavia. Archaeological evidence suggests that it was built in the later 10th century, during the period around 960 when Harald Bluetooth introduced Christianity into Denmark, as he proclaims on the larger of the two runic stones.
The part of the church burned down in 1679 and it was restored with a new porch. The pulpit dates from the 1650s. Mural paintings were in bad shape until Julius Magnus Petersen replaced them with copies in 1875. Jelling church is part of the UNESCO World Heritage site with Jelling mounds and runestones.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.
