Paris, the fashion capital, is a famous "city of lights", but there is another completely different "city of darkness"-the underground world of Paris. There are subways extending in all directions, criss-crossing underground canals, large parking lots, tunnels, cellars and a large number of skeletons and graves ... Not long ago, the Paris police accidentally discovered a very mysterious cinema underground. In addition to full-screen movie screens and projectors, the restaurants, bars and telephone facilities here are complete, which once surprised and confused people. In fact, this cinema is only a small part of the increasingly prosperous underground world in Paris. About 185 miles of underground passages, canals, subways, wires and cables constitute the "underground world" of the city, most of which are quarries in the past. These quarries have a long history and many stones used to build Paris come from here. The scale of the underground canal project in Paris is also very large. 50% of citizens' drinking water is imported through underground canals, and the storage capacity of underground pools is about1.2000 cubic meters. It is said that many underground canals still in use were built when the city was built in the 6th century. Now the government has opened many ancient canals for tourists to visit. In the deepest part of the underground world, there are still many "catacombs" quietly placed. It is said that there are 6 million skeletons in the catacombs in Paris, which is caused by the history of Paris. During the French Revolution and the Paris Commune Uprising in the18th century, there were many fierce battles in this city. During World War II, the French underground resistance movement also secretly dealt with Nazi German troops. In recent years, some of these tombs have been opened to the public, and all the tombs people have seen have undergone artistic processing: they have been piled into various shapes, including caves, corridors and arch bridges made of skulls, as well as bone walls made of other human bones. Numerous explorers have flocked to Paris for many years, and the diverse and ever-changing underground world of Paris is the unique landscape of the city. Nowadays, this strange and grotesque underground maze is becoming more and more attractive, and both young people who are keen on adventure and explorers in the city like to haunt it. As long as you enter the underground world, social class will cease to exist, and everything seems to have no boundaries. Photographer Patrick has been exploring the underground world of Paris for more than 20 years. He said: "Here, there is a feeling of double life." In this unusual place, people are used to holding flashlights in dark and humid spaces, and those quarries that smell musty are also named "cellars". Besides, poets and musicians often come here for inspiration. Some famous poems by the poet Henry Kazaris were born here, and anne rice, the author of Vampires, once imagined some horrible scenes here. Anecdotes will never stop. Although the underground world in Paris has been weird for decades, newspapers have reported all kinds of anecdotes, such as "underground social gatherings", "mysterious festivals and weird ceremonies" and so on. However, the mysterious modern cinema suddenly discovered by the police not long ago seems to tell people that today's underground world has become more complicated and strange. It is reported that this stepped cinema covers an area of 400 square meters and is equipped with a restaurant. There is also a small bar connected to the back door of the cinema. There are many tables and chairs in the bar, and the drinks and beer that have not been taken away are discharged on the table. The kitchen facilities behind the bar are also very advanced, and they are all electrified. Not long ago, in addition to this incredible cinema, the administrators of Sant Prison in Paris 14 district discovered several mysterious secret tunnels under the prison. According to the investigation, there are at least three underground tunnels in the prison, two of which lead to the observation post of the prison and the other to the prison gate. In addition, there are several shovels and some thick wooden stakes used to support the tunnel. Because all the prisoners in the prison are felons, the discovery of the secret way of God naturally aroused the high vigilance of the relevant departments in France. At present, it is not clear whether these paragraphs are related to escape or prison attack plans. However, the prison later said that these passages were actually passages of catacombs, and they were not dug recently.
