Saint Basil's Cathedral

The Cathedral of Vasily the Blessed (Russian: Собор Василия Блаженного, Sobor Vasiliya Blazhennogo), commonly known as Saint Basil's Cathedral, is a church in Red Square in Moscow, Russia. The building, now a museum, is officially known as the Cathedral of the Intercession of the Most Holy Theotokos on the Moat (Russian: Собор Покрова Пресвятой Богородицы, что на Рву, Sobor Pokrova Presvyatoy Bogoroditsy, chto na Rvu) or Pokrovsky Cathedral (Russian: Покровский собор). It was built from 1555–61 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 the ninth, central church of Intercession; the tenth church was erected in 1588 over the grave of venerated local saint Vasily (Basil). In the 16th and 17th centuries, the church, perceived as the earthly symbol of the Heavenly City, as happens to all churches in Byzantine Christianity, was popularly known as the "Jerusalem" and served as an allegory of the Jerusalem Temple...
