Abstract: The feasibility study of an underground laboratory in the Polkowice-Sieroszowice mine in Poland (SUNLAB) as a host of a far detector in a long-baseline neutrino oscillation experiment was performed. The SUNLAB location was previously studied under the LAGUNA FP7 project as a location for the underground multipurpose laboratory. The complementary study of the long-baseline neutrino experiment presented in this paper was performed as a continuation of this idea. A neutrino beam produced at CERN and a far LAr TPC detector hosted in the SUNLAB Laboratory were simulated. The sensitivity of such an experiment for the determination of the CP-symmetry violation in neutrino sector was calculated. The experiment at SUNLAB equipped with the 100 kton LAr TPC detector after 10 years of data taking can give the coverage of $\delta_{\mathrm{CP}}$ parameter space of 58\% (60\%) for the normal (inverted) neutrino mass hierarchy at $3\sigma$ level and in the both cases reaches $5\sigma$ level in the case of the maximal violation.
