has been funded by the French CNRS (Centre National de la Recherche Scientifique)
and the Italian INFN (Istituto Nazionale di Fisica Nucleare). The construction
of VIRGO required proficient skills in many advanced fields of science and technology.
Virgo is the result of a close collaboration between several hundreds of French
and Italian physicists and engineers belonging to eleven research laboratories.
Many industrial firms have also been involved in its realization such as CNIM
(F), SDMS (F), Pirelli (I), Belleli (I), Impregilo (I), Heraeus (D), VAT (CH).
