The Riddarholmen Church (Riddarholmskyrkan) is the burial church of the Swedish monarchs. The congregation was dissolved in 1807 and today the church is used only for burial and commemorative purposes. Swedish monarchs from Gustavus Adolphus (d. 1632 AD) to Gustaf V (d. 1950) are entombed here (with exceptions such as Queen Christina who is buried within St. Peter's Basilica in Rome), as well as the earlier monarchs Magnus III (d. 1290) and Charles VIII (d. 1470).
Riddarholmen church is one of the oldest buildings in Stockholm, parts of it dating to the late 13th century, when it was built as a greyfriars monastery. After the Protestant Reformation, the monastery was closed and the building transformed into a Protestant church. A spire designed by Willem Boy was added during the reign of John III, but it was destroyed by a strike of lightning on July 28, 1835 after which it was replaced with the present cast iron spire.
Coats of arms of knights of the Order of the Seraphim are in the walls of the church. When a knight of the Order dies, his coat of arms is hung in the church and when the funeral takes place the church bells are rung constantly from 12:00 to 13:00.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.
