About the book: 2020 / When it comes to holy places outside of Russia, Palestine is first remembered, less often Greece or Cyprus. But there are priceless shrines where, as many, unfortunately, believe there are none - in the same countries of Islam, for example, many of which are built on the ruins of Orthodox Byzantium. Finding hidden pearls is the main task. This will be discussed in this book, and the main object of study will be the south and west of Turkey. There are countless ancient cities there. The blood of martyrs of the first centuries of Christianity poured into them, and then churches, basilicas and martyriums were built at the places of their executions.
