Saudi Jeans posts on the existence of the ruins of Christian churches in Saudi Arabia, linking to sites that provide photos of an 4th C. CE Assyrian church in Jubail and one in Jeddah of unknown date.
There are also reports of pre-Islamic ruins of synagogues in Najran province, where Christians warred with Yemeni Jews in the 6th C. CE.
While Saudi Arabia doesn’t allow people of religions other than Islam to practice their faiths publicly here, the land of the Kingdom could be the home of one of the oldest churches in the region.
The Assyrian International News Agency website recently published some photos of what they called the Jubail Church, of which its ruins were accidentally unearthed in the 1980’s by a group of people attempting to dig their vehicle out of the sand. The website claims that the government has acknowledged the existence of this church but will not issue permits to visit it.
