It's right across the street from Denfert Rocherale Station on Line 4. The queue began at 2 p.m. and didn't enter until 4:30. There was more than one person in the queue. It's hot and sunny outside. It's cool to walk down the tunnel inside. It's better to wear a shawl or a thin coat. It takes half an hour to walk through the winding passage, with skeletons on both sides. It feels like a shock, because the skeleton Church in Italy has been ornate before. Compared with the pile here, it feels almost the same after seeing a few.
