Umm Al-Jimal, known as the Black Oasis, is a remarkable ancient city in the eastern desert of Jordan, built almost entirely from black basalt stone. It was recently added to the UNESCO World Heritage list.

The city flourished in the Roman, Byzantine and early Islamic periods, and it was an important stop on the trade routes. Its well-preserved houses, churches and walls give a vivid sense of life in the desert.

Umm Al-Jimal is known for its distinctive architecture, with multi-storey houses and a sophisticated water system. It is a peaceful, atmospheric site, far from the crowds.

It is an easy day trip from Amman, and it is often combined with the desert castles.
