Al-Ula

al-Ula (), officially AlUla, is an ancient Arabian oasis city and governorate located in Medina Province, Saudi Arabia, northwest of the city of Medina. Situated in the Hejaz, a region that features prominently in the history of Islam as well as several pre-Islamic Semitic civilizations, al-Ula was a market city on the historic incense trade route that linked India and the Persian Gulf to the Levant and Europe.

From an archaeological perspective, the immediate vicinity contains a unique concentration of precious artifacts, including well-preserved ancient stone inscriptions that illustrate the development of the Arabic language, and a concentration of rock dwellings and tombs that date from the Nabatean and Dedanite periods that coincided with Greco-Roman influence during classical antiquity. Saudi Arabia's first UNESCO World Heritage Site, Hegra (also known as al-Hijr, or Mada'in Ṣalih), is located north of the city, in al-Ula governorate. Built more than 2,000 years ago by the Nabataeans, Hegra is often compared with its sister city of Petra, in Jordan. Meanwhile, the ancient walled oasis city of al-Ula, locally known as al-Dirah, situated near the oasis's palm grove that allowed for its settlement, contains a dense cluster of mudbrick and stone houses. al-Ula was also the capital of the ancient Lihyanites (Dedanites).
