Stand at the foundation of the ancient Egyptian Obelisk ‘The Witness’ in St. Peter’s Square and a mind-boggling feeling starts to occur on you. The vast corridor seems to grasp you from the two sides, even as you extend your neck to appreciate the imposing exterior and the vault of St. Diminish's Basilica. Striking, stunning, speechless – a visit to the St. Subside's Basilica will leave you with numerous emotions. The largest church on the planet, St. Diminish's Basilica is something beyond the most significant structure in Christendom. It is a gem inside Vatican City from where Popes have spread the expression of God all through the world.
