By Living Waters: Jerusalem Ruins Point to Biblical Palace:

"Right now we have before us two things: We have a biblical text describing in detail the creation of a Phoenician-style palace by David high up on a particular mountain, around the end of the 11th or beginning of the 10 Century B.C.E. And we have a grand structure of the Phoenician style dating from the same time, on the summit of that very mountain, located with assistance from the text and previous archeological discoveries."
