Bethoron (also Beth-Horon) (House of Horon) was an ancient biblical town strategically located on the Gibeon-Aijalon road, guarding the "ascent of Beth-Horon". Upper Bethoron appears in Joshua 16:5 and Lower Bethoron in 16:3. 7:24.
According to 1 Chronicles 7:24, Lower Bethoron was built by Shira, daughter of Beriah, son of Ephraim. Eusebius' Onomasticon mentions the 'twin villages' and St. Jerome describes them as 'little hamlets.'  From Egyptian sources (Muller, As. und Europa, etc.) it appears that Bethoron was one of the places conquered by Shishak of Egypt from Rehoboam.
The borderline between Benjamin and Ephraim passed alongside the two Bethorons (Joshua 16:5; 21:22) who belonged to the latter tribe and therefore, later on, to the Northern Kingdom. Solomon "built Beth-horon the upper, and Beth-horon the nether, fortified cities, with walls, gates, and bars" (2 Chronicles 8:5; 1 Kings 9:17). One or both of the towns was a Levitical city (Joshua 21:22; I Chron. 6:53).
When (Joshua 10:10) Joshua utterly defeated the kings of the Amorites "he killed a large number of them at Gibeon, and chased them by the way of the 'Ascent of Beth-horon.'" When the Philistines opposed King Saul at Michmash they sent a company of their men to hold "the way of Beth-horon."
This pass ascends from the plain of Aijalon (now Ayalon-Canada Park) and climbs to Beit Ur al Tahta (1,210 ft.). It then ascends along the ridge, with valleys lying to north and south, and reaches Beit Ur al-Fauqa (2,022 ft.). Traces of the ancient Roman paving are visible. Since the days of Joshua (Joshua 10:10) the region has been the scene of many battles. The Syrian general Seron was defeated here by Judas Maccabeus (1 Macc. 3:13-24) in the Battle of Beth Horon. Six years later Nicanor, retreating from Jerusalem, was defeated and slain. (1 Macc. 7:39; Josephus, Ant. XII, x, 5). In 66 AD the Roman general Cestius Gallus was driven in headlong flight before the Jews.
Many centuries later, Bacchides repaired Beth-horon, "with high walls, with gates and with bars and in them he set a garrison, that they might work malice upon ("vex") Israel" (1 Macc. 9:50,51). Later, the Jews fortified it against Holofernes (Judith 4:4,5).
The two Palestinian villages of Beit Ur al-Fauqa and Beit Ur al-Tahta preserve part of the Canaanite name, and have been identified as the sites of Upper and Lower Bethoron. In 1915, the Palestine Exploration Fund wrote that changes in the main road to Jerusalem had left the Bethoron route "forsaken" and "almost forgotten".
Archaeological finds indicate that the lower town was established before the upper one. Potsherds from the Late Bronze Age onward were discovered at Lower Beit Ur, whereas those in Upper Beit Ur date only from the Iron Age onward.
