Cathedral of the Immaculate Conception

The Cathedral of Vasily the Blessed, commonly known as Saint Basil's Cathedral, is a Christian church in Red Square in Moscow, Russia and is regarded as a symbol of the country. The building, now a museum, is officially known as the Cathedral of the Intercession of the Most Holy Theotokos on the Moat. It was built from 1555 to 1561 on orders from Ivan the Terrible and commemorates the capture of Kazan and Astrakhan. It was the city's tallest building until the completion of the Ivan the Great Bell Tower in 1600. The original building, known as Trinity Church and later Trinity Cathedral, contained eight churches arranged around a ninth, central church of Intercession; a tenth church was erected in 1588 over the grave of venerated local saint Vasily (Basil).
The building is shaped like the flame of a bonfire rising into the sky, a design that has no parallel in Russian architecture.

The Sretensky Monastery is an orthodox monastery built in the 14th century. The modern monastery complex includes the Sreteniye Cathedral of the Vladimir Mother of God Icon with two chapels, galleries, a belfry and a few service buildings. The monastery is the place where the Our Lady of Vladimir met Muscovites in the late 14th century. At the meeting place with the icon (that is, Sreteniya), a wooden church was built in honor of the Vladimir icon, rebuilt in stone in 1679. In 1918 the monastery was closed, and from 1928 to 1930, all the churches, except the Our Lady of Vladimir, and almost all the buildings were destroyed. Since 1958, the cathedral housed the restoration workshops of I. Grabar. The monastery was reopened in 1995. It houses the largest Orthodox publishing house, the famous male choir, and a seminary.

The Moscow Cathedral Mosque is the main mosque of Moscow, the largest in Russia and Europe. The first building of the mosque was built in 1904, it housed a religious school which, after the revolution of 1917, became a secular Tatar school. During the Soviet period, the mosque did not close and even became the only functioning mosque in central Russia after 1936. With the 1980 Moscow Summer Olympics, the mosque, located next to the Olympic sports complex under construction, was threatened with demolition. The mosque was saved by Moscow's religious leaders and ambassadors from Arab countries. In 2011, it was demolished for the construction of a new mosque, which was opened in 2015.
