The Source, The Covenant, Alaska and Space.
The Source is such an amazing book, I've read it at least half a dozen times in the past 25 or so years since I first read it. It takes place primarily on an archaeologic dig in Israel in the 60s. As each level is revealed and artifacts found, the he takes you back to that time in history, all the way up to the present day of the book. The parts that take place in the kibbutz revolve around the discussions of the scientists and historians, an American, an Israeli and an Arab, at the dig about the Arab Israeli conflict.

The Covenant is the history of South Africa. https://en.wikipedia.org/wiki/The_Covenant_(novel)
Alaska and Space are pretty self-explanatory. I enjoy that, in most of his books, he takes the reader through an almost exhaustive history of a place, from pre-historic or the period of early man, and tells you the history in layers. Most importantly, except in the cases of characters and situations we know from history were truly immoral and malevolent, he doesn't take sides. He just tells the saga and events as they would have been experienced by every day people.
