The Siq (Arabic: السيق, transliterated al-Sīq, transcribed as-Sīq, literally 'the Shaft') is the main entrance to the ancient Nabatean city of Petra in southern Jordan. Also known as Siqit, it is a dim, narrow gorge (in some points no more than 3 metres (10 ft) wide) and winds its way approximately 1.2 kilometres (3⁄4 mi) and ends at Petra's most elaborate ruin, Al Khazneh (the Treasury). A wide valley outside leading to the Siq is known as the Bab as-Sīq (Gateway to the Siq). From Wikipedia
