Paris Catacombs
Writes elwer-gorse:
A huge network of passages that grew in the belly of Paris. The total length of the running in the tens of kilometers.
The initial emergence of developments related to the mining of limestone, which is under a thick layer of soil. Thus, the average depth of excavation was about 25 meters. This is far below the level of the Paris sewer and subway. Network moves mainly concentrated in central Paris. there are three most developed independent systems scattered under the busy street. Each of them developed independently at different times. I was able to visit the new and old system Denfert Rocherout ...
1.Shema catacombs. The winding sections - the old system (end of the XVIII century), direct - a new (mid XIX). The poster on the right compared with the occurrence of underground and sewage.
The new system is more monolithic. Hewn stone, straight narrow passages, the trace of which almost coincides with the trace of the streets. There are also branches in backlogs and third-party drifts.
The old system is more chaotic, masonry lined the aisle planed, sinuous moves. Here, a large number of branches and backlog. But the most interesting thing in her womb, more on that later.
