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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
