St. Basil's Cathedral is the anglicized name for the Russian Orthodox Cathedral of St Vasily the Blessed (also known as Pokrovsky Cathedral) which was built in the 16th century, and is situated on Moscow's Red Square in Russia.
In 1915, Rachmaninoff wrote a piece of music called All-Night Vigil Op. 37, which consists of settings for the Russian Orthodox All-night vigil service. Two pieces from the All-Night Vigil are repeated in the finale of his Symphonic Dances.
