We investigate multi-antikaonic nuclei (MKN), where several mesons are bound in the nucleus. We base our study on the relativistic mean-field theory, coupled with kaon-nucleon and kaon-kaon interactions which respect chiral symmetry. We discuss the effects of the nonlinear interaction, which is inherent in the chiral model, and on the properties of the MKN. We obtain density profiles for nucleons and mesons, the single particle energy of the mesons, and binding energy of the MKN by systematically changing (the number of the embedded ). We discuss the nonlinear repulsive effect, which makes the field saturate above a certain value of in nuclei. We also discuss a possible observation of the MKN in experiments.
