In this richly illustrated work, which originated on the precious anniversary of the arrival of our missionaries St. Constantine – Cyril and St. Methodius as well as on the occasion of the general repair of the Cathedral's interior, individual authors provide us with enriching views of the valuable Cathedral where the relics of St. Constantine – Cyril are housed and worshipped. They gieve us and apportunity to glance at the places which are not commonly accessible.
