Salzburg Cathedral is dedicated to two saints: Saint Rupert and Saint Virgil. The church on the original site was consecrated in 774 by Abbot and Bishop Virgil, who came from Ireland. That church was destroyed by fire, and construction was begun on the current cathedral in 1628. Unfortunately, the cathedral was bombed during World War II, but the damage was repaired after the war. The cathedral reopened for Mass in May 1959 after the repairs were complete.
I found the combination of gray and orange in the church to be particularly striking. The massiveness of the space makes one feel rather insignificant.
