Jerash, located in the north of Jordan, is one of the most impressive ruin sites of the Roman architecture outside Italy. Recent excavations show that Jerash was already inhabited during the Bronze Age (3200 BC - 1200 BC). After the Roman conquest (in 63 BC), Jerash and Philadelphia (now Amman), people were encouraged to devote their time and efforts in various developments including architecture.
The second half of the 1st century AD was a very productive and prosperous period for Jerash. The Emperor Hadrian visited Jerash in AD 129-130. The triumphal arch (or Arch of Hadrian, Photo 01) was built to celebrate his visit.
Later, Jerash suffered a series of earthquakes. In 749 AD, a major earthquake destroyed much of Jerash and its surroundings. Jerash was buried in the sand and ashes until a German traveller discovered it in 1806. The current excavation and restoration has been a continuing one since 1920.
