In the 18th year of his reign (20–19 BCE), Herod rebuilt the Temple on "a more magnificent scale". Although work on out-buildings and courts continued for another 80 years, the new Temple was finished in a year and a half. To comply with religious law, Herod employed 1,000 priests as masons and carpenters in the rebuilding. The finished temple, which was destroyed in 70 CE, is sometimes referred to as Herod's Temple. Today, only the four retaining walls remain standing, including the Western Wall. These walls created a flat platform (the Temple Mount) upon which the Temple was then constructed.
