Walking the path up to biblical Tel Lachish, surrounded by the vineyards grown here since antiquity, you'll pass through a gateway the Babylonians must have stormed in 586 CE.
Here, the famed Lachish Letters were unearthed, written on potsherds to the city's commanders before the Babylonians conquest. You'll see a massive siege ramp, a remnant of the Assyrian King Sennacheribs destruction.
You'll also see remains of a huge First Temple-era palace and peer into a well, over 120 feet deep, which provided water to the city in First Temple times.
Always open (depending on the weather conditions & during daylight).
