The partially excavated archaeological site consists mainly of an extensive necropolis of rock-cut tombs and some remains of the town itself. The site is managed by the National Parks Authority as the Beit She'arim National Park. It borders the town of Kiryat Tiv'on on the northeast and is located five kilometres west of Moshav Beit She'arim. It is situated 20 km east of Haifa in the southern foothills of the Lower Galilee.
In 2015 it was declared a UNESCO World Heritage Site. The rationale of the committee was as follows: The town's vast necropolis, carved out of soft limestone, contains more than 30 burial cave systems. Although only a portion of the necropolis has been excavated, it has been likened to a book inscribed in stone. Its catacombs, mausoleums, and sarcophagi are adorned with elaborate symbols and figures as well as an impressive quantity of incised and painted inscriptions in Hebrew, Aramaic, Palmyrene, and Greek, documenting two centuries of historical and cultural achievement. The wealth of artistic adornments contained in this, the most ancient extensive Jewish cemetery in the world, is unparalleled anywhere.
According to Moshe Sharon, following Yechezkel Kutscher, the name of the city was Beit She'arayim or Kfar She'arayim (the House/Village of Two Gates). The ancient Yemenite Jewish pronunciation of the name is also "Bet She'arayim", which is more closely related to the Ancient Greek rendition of the name, i.e. Βησάρα, "Besara".
The popular orthography for the Hebrew word for house, בֵּית, is "beit", while the traditional King James one is "beth", the effort being now to replace both with the etymologically better suited "bet".
Pottery shards discovered at the site indicate that a first settlement there dates back to the Iron Age.
