BRATISLAVA, SLOVAKIA—According to a report in The Slovak Spectator, a joint Kuwaiti-Slovak archaeological team working at the Nestorian Christian settlement of Al-Qusur on Failaka Island in the Persian Gulf unearthed a palace dating from the seventh to ninth centuries, a sewerage system, and the base of a stone tower. “According to a preliminary analysis, it’s a unique so-called windcatch-tower, utilizing an ingenious interior cooling system based on the flow of air, caught by openings in the tower superstructure,” Matej Ruttkay, director of the Slovak Academy of Sciences’ Archaeological Institute, told the TASR newswire. Similar cooling systems have been found in the Middle East and North Africa. To read in-depth about the site, go to "Archaeology Island."
