For safety and scientific reasons, the access to the Virgo site is limited. However EGO regularly welcomes visitors so that they can learn more about Virgo.

Guided tours of Virgo are free for all visitors, and priority is given to schools and academic institutions. However associations, groups of people, or whoever is interested in discovering the interferometer are warmly invited to come too.

Site visits must be booked at least four weeks in advance, considering the following:
  • as a general rule, visits are restricted to Tuesday or Saturday mornings;
  • individual requests are collected until a minimum number of 15 visitors is reached;
  • group visits shall be limited to maximum 60 visitors since no more than 30 persons at a time may visit the internal parts of the interferometer buildings.

  • To have more information on tours at Virgo or request the booking form, call at +39 050 752 511 or send an email to info(at)
    To reach the site of EGO, follow the indications available here.

    Note that because of the current high demand of visits, any new request will be put on a waiting list of more than one year.
    We are sorry about that and do our best to fulfil these expectations.
