The Amman Citadel is a national historic site at the center of downtown Amman, Jordan. Known in Arabic as Jabal al-Qal'a, (جبل القلعة), the L-shaped hill is one of the seven jabals that originally made up Amman. Evidence of occupation since the pottery Neolithic period has been found, making it among the world's oldest continuously inhabited places. The great temple of Hercules (Herakles) was built between 162-166 AD. Larger than any temple in Rome itself, the massive structure faces east and is seen here from the front (northeast corner.) The temple portico is framed by six 33-foot tall columns. The absence of columns on the rest of the structure, has convinced the excavator that the temple was actually left unfinished.
