The Tomb of the Unknown Martyr One channel video/Sound installation. 2014 In 21st of October 1970, the Palestine Liberation Organization (PLO) built a monument on top of a mass grave in Jabal Al-Ashrafiyeh. The monument was to commemorate the martyrs who were slaughtered in the massacres known as Black September, during the jordanian civil war in 1970. In 31st of May 1971, the monument was demolished by the jordanian military forces, at the same time most of the documents about the massacres were destroyed with the intention of eliminating the collective memory of the civil war and the palestinian political presence in Jordan. The project consists of an exact replica of the original memorial installed in April 2014 in the plaza of Jabal Al-Ashrafiyeh.
