Siq

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, the main entrance in Petra is a dim, narrow gorge (in some points no more than 3 metres (10 ft) wide) winds its way approximately 1.2 kilometres (0.75 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).
