The Tower of Elahbel (also known as Tower 13 or Kubbet el 'Arus) was a four-storey sandstone tower tomb near the ancient city of Palmyra in Syria. The tower was one of several built outside the city walls of Palmyra, in an area known as the Valley of the Tombs. The tower was important in the history of textiles: fragments of very early Chinese silk yarns, dated to the 1st century AD, were discovered in the tombs at the tower. The tower was demolished using explosives by the Islamic State of Iraq and the Levant in August 2015.
