Eilat Mazar was an Israeli archaeologist. She specialized in Jerusalem and Phoenician archaeology. She was also a key person in Biblical archaeology noted for her discovery of the Large Stone Structure, which she surmised to be the palace of King David.

The Large Stone Structure is the name given to a set of remains interpreted by the excavator, Israeli archaeologist Eilat Mazar, as being part of a single large public building in the City of David, presumably the oldest settlement core of Jerusalem. Mazar tentatively dated the findings to the tenth to ninth century BCE. Mazar chose this particular name for the alleged structure because of its proximity to another site known as the Stepped Stone Structure. Mazar announced the discovery on 4 August 2005, and stated that she believed it may be the remains of King David's palace as recorded in the Books of Samuel. The interpretation of the remains as those of one single building, the suggested date, and the association with King David have all been challenged by other well-known archaeologists. The archaeological dig was funded privately by Roger Hertog, an American banker.
