The proper name of this whimsical structure is Church of the Intercession. It was commissioned by Ivan the Terrible to celebrate his conquest of the Tatar city of Kazan on October 1, 1552, the day of the feast of the Intercession. The central chapel, which rises 107 feet, is surrounded by eight towerlike chapels linked by an elevated gallery. Each chapel is topped by an onion dome carved with its own distinct pattern and dedicated to a saint on whose day the Russian army won battles against the Tatars. The cathedral was built between 1555 and 1560 on the site of the earlier Trinity Church, where the Holy Fool Vasily (Basil) had been buried in 1552. Basil was an adversary of the tsar, publicly reprimanding Ivan the Terrible for his cruel and bloodthirsty ways. He was protected, however, from the tsar by his status as a Holy Fool, for he was considered by the Church to be an emissary of God. Ironically, Ivan the Terrible's greatest creation has come to be known by the name of his greatest
adversary. In 1558 an additional chapel was built in the northeast corner over Basil's remains, and from that time on the cathedral has been called St. Basil's.
Very little is known about the architect who built the cathedral. It may have been the work of two men—Barma and Postnik—but now it seems more likely that there was just one architect, Postnik Yakovlyev, who went by the nickname Barma. Legend has it that upon completion of the cathedral, the mad tsar had the architect blinded to ensure that he would never create such a masterpiece again.
After the Bolshevik Revolution, the cathedral was closed and in 1929 turned into a museum dedicated to the Russian conquest of Kazan. Although services are held here on Sunday at 10 am, the museum is still open. The antechamber houses displays that chronicle the Russian conquest of medieval Kazan as well as examples of 16th-century Russian and Tatar weaponry. Another section details the history of the cathedral's construction, with displays of the building materials used. After viewing the museum exhibits, you're free to wander through the cathedral. Compared with the exotic exterior, the dark and simple interiors, their brick walls decorated with faded flower frescoes, are somewhat disappointing. The most interesting chapel is the main one, which contains a 19th-century baroque iconostasis.
