St. Isaac's Square, along with Palace Square, plays a central role in St. Petersburg's life – as a commercial, administrative, spiritual and cultural centre of the city. Commercial and administrative – in that around the square we find many governmental agencies, institutions and business organisations. Spiritual, in that we find St. Isaac's Cathedral at the very centre of the square. And cultural, because the square is a nucleus of many museums, and similarly buildings connected with the lives of major cultural figures – as you will see and hear during our tour.
