Stephen Cathedral, the exterior of the church is still under repair, but there are still a lot of visitors. The church is a combination of architectural styles, and the North Tower overlooks the new city of Vienna, while the South Tower is the third tallest church steeple in the world. During the visit, the mosaic on the roof of the church was particularly interesting. It was composed of yellow, green and black, and the two-headed eagle representing the Habsburg dynasty was the most eye-catching. The open area inside the church was not too big, and it was soon finished, and a beam of light on the ground through the glass made people feel sacred and solemn.
