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 Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
