I want to know the answer to the following question:
Where can view the network of tunnels to the catacombs?
All the background I'm provided with is that "In Paris' Roman era, its main cemetery was located to the outskirts of the Left Bank settlement, but this changed with the rise of Catholicism, where most every inner-city church had adjoining burial grounds for use by their parishes.". Is that enough to answer the question?
Answer: no
