St. Basil's Cathedral was built to commemorate the capture of the Tatar stronghold of Kazan in 1552, which occured on the Feast of the Intercession of the Virgin. It is named after St. Basil the Blessed. Basil impressed Ivan in 1547 when he foretold a fire that swept through Moscow that year. Upon his death, Basil was buried in the Trinity Cathedral that stood on this site at the time. The cathedral was constructed from 1555 to 1560. In 1588, Tsar Fyodor Ivanovich added a ninth chapel added on the eastern side to house the grave of St. Basil.
St. Basil"s Cathedral consists of nine chapels built on a single foundation. The riot of color and shapes that is St. Basil"s Cathedral is unmatched anywhere else in the world. The powerfully eastern design of St. Basil"s reflects both its location between Europe and Asia and its historical origins. Since the Kazan Qolsharif mosque had been the principal symbol of the Khanate captured by Ivan the Terrible, some elements from the mosque were incorporated into the cathedral to symbolize the victory.
Although the towers and domes appear chaotic, there is symmetry and symbolism in its design. There are eight domed chapels symbolizing the eight assaults on Kazan: four large and octagonal and four small and square. In the center is a tent-roofed spire topped with a small golden dome. The ninth chapel on the east side added in 1588 for Basil"s tomb interrupts the symmetery of design somewhat. It can be recognized on the outside by its green-and-gold dome studded with with golden pyramids.
The interior is a maze of galleries winding from chapel to chapel and level to level via narrow stairways and low arches. The walls are painted in floral and geometric patterns.
St. Basil the Blessed can be visited in his chapel on the lower floor, where he lies in a silver casket in gaudy splendor. Upstairs, the Chapel of the Intercession contains the equally splendid blue and gold iconostasis. Other chapels, such as that of St. Nicholas, are more restrained and even austere in their decor.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
