The park will be centered on its dolmens, the prehistoric chamber tombs found there. Read the background and view a few photos. This site is about the 10th century civilization of the Khazars. The Khazars had built a Jewish empire in the heart of the Black Sea region. You will have to do some searching in this website to find the archaeological information as opposed to straight history, but there is a lot of it once you 'uncover' it.
Some articles are in Russian only and others are English.
Forget the first archaeology links you come to unless you read Russian. Further down the page is where you will find the English links. The Khazaria Info. You will find expedition reports, photos, and history of the area. Links to articles with photos are scattered throughout the text.
