Very High-Energy cosmic rays have to be studied through the ground-based detectors of the Extensive Air Showers (EAS) that they produce in the atmosphere. The main measurements to be performed are of: primary energy spectra, composition, anisotropies, «neutral primary» astronomy, and interaction properties. This requires complete detectors of all the EAS components, and for this purpose the EAS-TOP array has been constructed at Campo Imperatore (2000 m a.s.l.) on top of the Gran Sasso underground laboratories. The array has been progressively going into operation since 1988. In this paper we present the status and performances of the different detectors, and the results obtained up to now on the different items under discussion.
