There is a city that i learned about in Jewish teachings called Luz. This city was unconquerable and every kingdom that tried to conquer them inevitably failed. We learn that this city was given special protection by G-d which is why none could conquer it. Luz is located in what was once the kingdom of the Hitites, north of Syria; by my calculations this is modern-day Turkey. I was wondering if anyone knew of similar stories in other religions or what-not.
Me'am Loez is usually based on older sources the author had, so it's always worth trying to locate the original sources. In this case, there are a few Talmudic sources that attest both realistic and legendary qualities to a city in the Province of Syria named Luz. See
BT Sotah 46b,
BT Sanhedrin 12a. Jastrow
brought a suggestion that Luz is to be identified with Lizan/Leezan, a village in Kurdistan, northeast of Mosul (some sources:
1,
2). According to the Encyclopedia Mikra'it (Hebrew Biblical Encylcopedia), some have suggested that it should be identified with
Luwayza in Lebanon or
Khirbet al-Luwayza. However, the author of the entry himself found both suggestions unlikely.
On the legendary qualities of this city, see Marc Bregman's
article. Bregman thought the city was like a Jewish Shangri-La, so that's relevant to what you're looking for.
