Underneath parts of Edinburgh, there are complete streets which have
been built over and are now open to tourists.

This is true in some U.S. cities as well, such as Seattle that was re-built at
least once (I believe it's actually been rebuilt several times -- fire did it
in once too) after severe flooding in the city's early days. The original
"street level" is something like 10' below the current "street level."

It is really cool to see all these old underground "ghost" towns.
