Cathedral of St. Michael and St. Gudula

The city of Brussels, although the capital of Belgium, is nearly a thousand years older than the country itself. This Cathedral of St. Michael and St. Gudula was built as early as 1047, and at that time it should have been dedicated to St. Michael (who is the archangel), and later it was upgraded to a two-saints cathedral after receiving the relics of St. Gudula (who was a devout female believer and was called a saint because of her lifelong service to the Lord). The front of the church resembles the Notre-Dame de Paris (unfortunately, it suffered a big fire and was under repair when I visited), and the self-guided tour inside has Chinese explanations, introducing the design and the twelve apostles of the church. The stained glass windows of the church are full of stories, but unfortunately I don't know the specifics.
