St. James Church dates from the seventeenth or eighteenth-century. Together with different tserkvas it is designated as part of the UNESCO World Heritage Site 'Wooden tserkvas of the Carpathian region in Poland and Ukraine'.
The tserkva in Powroźnik has existed since around 1600, but only a part of the former structure remains, arranged into the sacristy of the present tserkva. The architecture of the present tserkva was constructed between the seventeenth and eighteenth-century, with a major reconstruction in 1813. The tserkva was moved from its former location due to the danger posed by flooding, after which it was expanded. After Operation Vistula the tserkva was transformed to a Roman Catholic church.
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.
