Welcome to the Vienna State Opera, which stands along the Opernring, one stretch of the great boulevard that circles Vienna's historic center. Take a moment to look at the building in front of you. It is both an opera house and the home of an opera company, and it counts among the busiest opera houses in the world. The house seats 1,709 people, and its style is Renaissance Revival. It was the first major building to rise on the Ring Road, so in a sense it set the tone for everything that followed along this avenue. Over the next few minutes we will look at how the boulevard came to exist, who designed the house, how its name changed with the fall of an empire, and how it was wrecked and brought back after the Second World War. There is a lot to hear, so settle in. This is a building that still works hard every single evening, and it carries layers of history in its walls.
