Under all the cities of the antediluvian civilization, brick tunnels for underground transport were laid, in which the passage was closed. Thanks to diggers, we can still see this incredible architectural marvel underground.
And who now admits that in the second half of the 19th and at the beginning of the 20th century, pneumatic subways clogged with clay were dug out in Europe, then the antediluvian tunnel systems were restored and completed? The first London Underground line opened in 1863. in New York in 1868. French subway in Paris - in 1900. Its construction began with a project in 1871, with the discovery, again, of those old, mud-filled tunnels of an antediluvian pneumatic subway.
