nroff input for man pages is kept in /usr/share/man/manX, compressed with gzip to save space.  'man' knows how to uncompress on the fly.

Formatted versions of the manuals are kept in /var/cache/man/catX.  Should the directory be writable, man will also deposit the formatted pages as they are created, generating a cache of commonly read man pages.

'manpath' will display the path 'man' utilizes when searching for manual pages as per your request.  The system wide default can be configured in /etc/man.config (on some distributions)  The PAGER environment variable controls the way inwhich the listing of the man pages is utilized, typically using 'less'.
