Standing stones (high places, bamah) are often found at the gate of Biblical cities. The photo below shows some standing stones from the gate of Tel Dan. The informational sign immediately to the left of the standing stones includes a quotation from 2 Kings 23:8. The text describes the reforms of King Josiah of Judah (641/40–609 B.C.).
He brought all the priests from the cities of Judah and ruined the high places where the priests had offered sacrifices, from Geba to Beer Sheba. He tore down the high place of the goat idols situated at the entrance of the gate of Joshua, the city official, on the left side of the city gate. (2 Kings 23:8 NET)
[On “goat idols” see Leviticus 17:7 and 2 Chronicles 11:15]
Here is a closer view showing the standing stones. The placement of these stones at the gate of the city allowed everyone who came into the city to make obeisance to whatever god was represented.
