Amman, the capital of Jordan, was originally built on seven hills (jabals), much like Rome. Today, however, the city has sprawled to cover at least 19 hills. Amman is one of the oldest continuously inhabited cities in the world, with archaeological finds at the site of 'Ain Ghazal dating back to 7250 BC. In ancient times, the city was known as Philadelphia, named after the Ptolemaic ruler Ptolemy II Philadelphus. The most iconic site is the Amman Citadel, which sits on the highest hill and contains the Temple of Hercules, a Byzantine church, and the Umayyad Palace. Below the Citadel lies a remarkably preserved 6,000-seat Roman Theater that is still used for cultural events today. Amman is a fascinating mix of old and new; while the 'Downtown' area preserves traditional souks and street food, the western districts feature modern malls and luxury hotels. It is known as one of the most liberal and westernized Arab capitals, serving as a peaceful hub for refugees and business in the heart of the Levant.
