Millo
The Millo (Hebrew: המלוא) was a structure in Jerusalem first mentioned in the book of 2 Samuel 5:9 and corresponding passages in the Books of Chronicles and the Books of Kings. However it is mentioned as being part of the city of David and seems to have been a rampart built by the Jebusites prior to Jerusalem's being conquered by the Israelites. The texts also describe a Millo built by Solomon and repaired by Hezekiah, without giving an explanation of what exactly the Millo was. There is some debate among scholars as to the Millo's specific nature. The most common assumption among archaeologists and historians of ancient Israel is that the Millo is the Stepped Stone Structure uncovered by Kathleen Kenyon and demonstrated by Eilat Mazar to be connected to the recently uncovered Large Stone Structure.
