Throne of Earthly Kings is by Francois Hameury and is sited in the courtyard of Devonport House in Greenwich, now part of the University of Greenwich. It dates from 2004.
There is very little recorded information on the statue but apparently he words inscribed on the base are:
May all who sit here have the courage to be true to themselves. The world is a kingdon for those who search inside. Francois Hameury 2004
