Possible Location for the Underground Laboratory in Poland

First measurements of neutrinos from the Sun in 1964 and from the supernova explosion in 1987, and recent discoveries of the oscillations of atmospheric and solar neutrinos caused that the physics of natural neutrinos became the important field of studies and that the neutrino astronomy was born. It is clear that neutrinos are important messengers from stars. Another big but still open question concerns the proton decay, predicted by Grand Unification Theories aiming at the unification of fundamental forces in Nature. Achieving significant progress in both studies requires huge detectors on the 100 - 1000 ktons scale, i.e. by one to two orders of magnitude larger than the existing ones. At present there is no single infrastructure in the world which could host such detectors. The LAGUNA project aims at looking for the possible localization in Europe, in agreement with the ApPEC road map. Although studies of the low energy neutrinos from astrophysical sources and searches for proton decay are of the primary interest, the localization should take into account the possibility of neutrino studies with accelerator neutrino beams. One of the possible locations of the new infrastructure is in Poland. In this presentation the proposed localization of mentioned detector in old copper mines in Polkowice-Sieroszowice is discussed
