A journey is more joyful with true books. There are many sources on the internet and in the bookstores about Biblical places in Turkey. I strongly recommend to have a book with you whilst your travel in Turkey. My personal favorite is “Biblical Turkey, A Guide to the Jewish and Christian Sites of Asia Minor” by Mark Wilson. You will be able find the information about all the Biblical places with related verses from the scriptures. Moreover, the site photographs and maps will give you a general idea about the region.
