The site has two parts, Journey and History, which you can see on the navigation menu bar above. So if one of these subjects interests you a lot and the other not so much, sorting them out won’t give you much trouble. Photo Galleries is not another part, just a convenient menu of all the picture pages.
As you no doubt know, Greek is written in a different alphabet from English. (And as Greeks would point out, it’s also an older alphabet, from which the Roman one we use was derived.) Anyone traveling to Greece would be wise to learn it, even not knowing the language—if nothing else, it can help you figure out the place names on road signs. On this site, however, I've used our alphabet to transcribe Greek names and other words in a way that I hope will help make them easier (if not exactly easy) to pronounce. The system I used is described here.
