In the UAE, archaeologists found the ruins of a settlement that is believed to be a lost city of the sixth century   

Research conducted at Umm al-Quwain indicates that archaeologists have been able to discover the ancient city of Tuam, which was once the center of the Persian Gulf coast and was known for its pearl catches of high quality. Tuam was known in the 6th century and mentioned in ancient Arabic texts. However, after an epidemic of plague and tensions in the region, the city fell into decline. Excavations conducted in recent years on the island of Al-Sinnia have allowed archaeologists to argue that this site may be a long-forgotten city. This year, the excavations have found remnants of ancient residential buildings - large buildings with courtyards that speak of a thousand-year settlement with a developed social structure. The settlement on Al-Sinnia Island existed at least since the 4th century and reached its heyday in the 5th and 6th centuries. At this time, the Nestorian monks who founded one of the first Christian monasteries in the territory of the modern UAE arrived. Archaeologists are reconstructing the history of development of the settlement, which occupied about 10 hectares. First there were small stone buildings, then, thanks to the pearl trade, the city expanded to appear larger and more richly decorated houses for traders. These findings confirm the activity of trade links with Iraq, Persia and India. In addition, this year archaeologists discovered a pitcher with inscriptions in the ancient Aramaic language that was spoken in the region before the arrival of Arabic. This is a sign of the high level of trade and cultural ties among the inhabitants of this city.
