The new city of Kalmar built on Kvarnholmen around the mid-1700s. The transfer from the old town was largely completed in 1658. The new, fortified town was planned after the current renaissance ideals. According to this pattern were placed Kalmar Cathedral and town hall across from each other at a major square Stortorget Kalmar. The cathedral was built, designed by Nicodemus Tessin the Elder and is one of the foremost examples of Baroque breakthrough in Sweden. Kalmar Cathedral drawing series reflects the complex interaction between the new style, liturgical considerations, tradition and the fortress-city requirements. The work began in 1660, but it was interrupted on several occasions, including when the Scanian War (1675–1679) raged. Construction resumed, and Kalmar Cathedral stood finished in 1703.
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.
