JERICHO, WEST BANK Oct 28 (Reuters) - One of the largest mosaic panels in the world has been unveiled after a $12 million multi-year restoration project at Hisham’s Palace in Jericho in the occupied West Bank. The Palestinian Ministry of Tourism and Antiquities on Sunday unveiled the Umayyad-era mosaic, a total of 38 carpet-like mosaic panels covering 827 square metres. Elevated platforms were built to assure that the visitors can enjoy the site of the mosaic without treading on it.
