Bahra 1 is a large Ubaid-period site in the Al-Subiyah region in Northern Kuwait which combines Ubaid and Arabian Neolithic characteristics, proving intensive contacts with Mesopotamia in the second half of the 6th millennium BC. Of particular interest was Unit 6 with an oval courtyard surrounded by a stone enclosure and fireplaces and fire-pits in two occupation phases. Several fireplaces were found also in an older level, apparently of a distinctly different character. Unit 14 showed the first case of a shelter being built into natural rock feature, while the remains under Unit 3, presenting a different spatial layout than later structures, indicated a period of abandonment of some duration between successive phases. The rich pottery collection of over 6200 fragments was broken down into nearly equal shares of Ubaid ware and Coarse Red Ware. The lithic material (over 30,000 tool fragments and debitage) formed a specialized assemblage dedicated to the production of tubular shell beads, adding to the evidence already collected for the existence of bead workshops at the site. An exceptional find was a copper object from one of the older layers of the settlement.
