EGO - the European Gravitational Observatory - is located in the countryside near Pisa in the Commune of Cascina.
In order to ensure the long term scientific exploitation of the VIRGO
interferometric antenna for gravitational waves detection as well as to foster European collaboration in this upcoming field, the VIRGO funding institutions (CNRS
for France and INFN
for Italy) have created a consortium called EGO (European Gravitational Observatory).
VIRGO is a 3-km long interferometer built in the framework of a French-Italian collaboration. Today, this collaboration involves 17 laboratories
with more than 190 scientists in France, Italy and also in the Netherlands and Poland as well.
