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 inside. 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. A model of the temple is displayed at ACOR, the American Center for Oriental Research in Amman.
