The Cathedral of Saint Jean of Lyon is the cathedral of the Catholic Archdiocese of Lyon. The cathedral was first built in the 12th century and completed in 1476, and was built for three centuries. The church is both Roman and Gothic, with an interior of 80 meters long and 20 meters wide, a mid-temple height of32.5 meters, and a 14th-century astronomical clock. Before the construction of Notre Dame de Fuvière, the cathedral was the most majestic church in Lyon. The coronation of Pope John XXII and the grand wedding of King Henry IV and Queen Mary de Medici were held here, which shows its great reputation. It is also understood why its name has the word "chief". The style of the cathedral is somewhat different from the Notre Dame on the top of the mountain, and the artwork displayed inside is also somewhat different. Apart from the stained glass window paintings, the large oil paintings on the surrounding walls are particularly impressive. In addition, there are two tower-like artworks inside the church, one is a typical Gothic church, said to be a fourteenth-century astronomical clock, performed several times a day, and the other is a "Linglong Tower" filled with sculptures of many biblical figures.
