Kizichesky Vvedensky Monastery is a small male monastery in Kazan. It was founded in 1691 by Adrian—the Moscow Patriarch, who until 1690 were the Kazan Bishop. The name Kazichesky means Holy Martyrs of Cyzicus. The monastery was devoted to the martyrs because parts of their relics were brought to the monastery—according to the wishes of Adrian. In the 1690s Vvedensky Cathedral and Vladimirskaya Church were built. Vvedensky Cathedral was destroyed during the Soviet epoch. Ilya Andreevich Tolstoy (the grandfather of Lev Tolstoy) is buried in the monastery.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.
