The ruins of the mosque, believed to be more than 1,200 years old, were discovered during construction work on a new neighborhood in the Bedouin city of Rahat, the Israeli Antiquities Authority (IAA) said in a statement. The mosque, located in the Negev Desert, contained a square room and a wall facing Mecca, with a semicircular niche in this wall pointing south, the IAA said.

A short distance from the mosque, a “luxury building” was also discovered, with remnants of tableware and glassware showing the wealth of its inhabitants, the IAA said.

The IAA said the mosques found in Rahat would be preserved at their current locations, either as historical monuments or as active places of worship.
