We visited St. Severin's Church in Paris with a guide. Unfortunately, they didn't get inside, because the funeral and service were taking place there. There is a very beautiful large cathedral building outside. It was built around the XV century. Very beautiful stained glass windows. We will try to visit Paris next time.
A flaming Gothic church in the Latin Quarter. The 1412 Macée bell, the oldest bell in Paris, is located here. Interestingly, the church was first built, and then 120 years later it was rebuilt after the Hundred Years' War using the proceeds from the sale of indulgences organized by Popes Clement the Sixth and Calixtus the Third.
