Kazan Cathedral — one of the largest churches of St. Petersburg, made in the Empire style. Built on Nevsky prospect in 1801-1811 by the architect A. N. Voronikhin. After the Patriotic war of 1812 became the monument of Russian military glory. In 1932, transformed into a Museum of the history of religion and atheism, since 1991, the current temple. Since 2000, the Cathedral of St. Petersburg diocese of the Russian Orthodox Church. The Cathedral gave the name to the street of Kazan, the Kazan island in the Delta of the Neva river and the Kazan bridge on the intersection of Nevsky Prospekt and the Griboyedov canal.
July 2, 1737, was moved to the Kazan icon of the Mother of God. In Saint Petersburg this relic that belonged to the tsarina Praskovia Fedorovna, was brought under Peter I in 1708. To the transfer to the new Church she was kept in a wooden chapel on Posadskaya street, then at the Holy Trinity Cathedral on Trinity square. The consecration of the Church took place on 13 June (according to the historian P. J. Kahn), 3 July 1737. The second option seems more logical considering the date of the transfer of the Kazan icon here. The ceremony was attended by Anna Ioannovna. Stored here the icon of the Church people began to call "Kazan".
