The Exploratory story begins with the dream of one man more than 350 years ago.
In 1627 the scientist and philosopher Francis Bacon described an imaginary science centre designed for both amusement and hand-on investigation of scientific phenomena in his unfinished book The New Atlantis.
This dream did not become reality until 1969 when the Exploratorium was founded in San Francisco by the US scientist Frank Oppenheimer.
It was this place that inspired Professor Richard Gregory, CBE, of the University of Bristol, to start up the Exploratory in 1983 - the first hands-on science centre in the UK.
By the time The Exploratory closed finally on September 1st 1999 it had attracted over two million visitors.
