Sretensky Monastery

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 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.

The Cathedral of the Immaculate Conception of the Holy Virgin Mary is a neo-Gothic Catholic Church at Moscow's center, that serves as the cathedral of the Catholic Archdiocese of Moscow. Located in the Central Administrative Okrug, it is one of three Catholic churches in Moscow and the largest in Russia. The construction of the cathedral was approved in 1894 by the Ministry of Internal Affairs under Tsarist Russia. Groundbreaking was in 1899; construction work began in 1901 and was completed ten years later. Three-aisled and built from red brick, the cathedral is based on a design by architect Tomasz Bohdanowicz-Dworzecki. The style was influenced by Westminster Abbey and Milan Cathedral. In 2002 it was elevated to the status of cathedral. Following an extensive and costly program of reconstruction and refurbishment, the cathedral was reconsecrated in 2005. In the 21st century, the cathedral is once again the setting for regular liturgical celebrations in multiple languages—Russian, Polish, Korean, English, French, Spanish, Armenian and Latin—as well as benefit concerts featuring organ and church music. The cathedral is listed as a heritage building in the Russian Federation, and is a protected monument.
